How often must I change synthetic oil ?

My Nissan has 60K on the engine and, I normally use conventional oil and, change every 3K. Id like to try synthetic oil but, need to know how often it needs changing.How often must I change synthetic oil ?
It's not just the dirt, but the breakdown of the viscocity of the oil that makes it 'wear out'. This is why synthetic can go longer - it lasts longer in that respect.





5k is a good general rule. A change before that is just wasting money.How often must I change synthetic oil ?
Just as often as your car manufacturer recommends for regular oil, most likely 3-5k. Here is my reasoning, your oil will still get as dirty at the same rate as conventional oil, if at 3k it is still clean, keep going, you be the judge. I live on a gravel road, so my oil is dirty enough to change at 3k.
I have used synthetic for years in a F-150 with 180,000K on it and I change the oil at 15,000K and replace the filter every 7500K.The majority of my driving is done on bush roads, and the trucks does not burn any oil.In our car I used conventional oil and change it every 5,000K
Same as with conventional oil. The reason you change oil is because it gets dirty. Synthetic oil gets dirty just as fast as conventional oil.
5000 miles
7500
Ifn you drive like a racer then 4000 if normal 5000 to 6000 if you dont drive very long distances or hardley at all then 7000
Everyone is going to argue this. But it would be ok with just changing it every 6000 Miles.

I have a question about Royal Purple Synthetic Oil ?

I have been using synthetic oil in my car when i get oil changes, but recently i came across a royal purple synthetic oil commercial. I noticed that it advertises more horsepower and torque, improve fuel economy and emissions, reduce engine wear etc. I also noticed it's a little bit more expensive then the synthetic oil i buy. My first question is, does it do all that is says it do, as far as more power, better fuel economy etc and is it worth the extra money.I have a question about Royal Purple Synthetic Oil ?
Well that is a very general statement that would apply to changing your oil in general. Synthetic oil is better than conventional oil but one brand from the next is the same. Basically the only difference is in the additive packages. Some oils have better additive packages in them. That is what really makes a good oil. Not so much the brand. I always recommend Mobil 1 not because I think it is better but because if you need to add a quart and are out of town you will have no problem finding it will try and find royal purple or am soil and forget about it. But like I said above putting any new oil in a car can give you those statements they said.I have a question about Royal Purple Synthetic Oil ?
I stick with the oil my car has always used, and don't change the brands or kind I have put in ========
You already have all the advantages of using a synthetic oil. Any name brand synthetic oil available at the shops you have your oil changed at meets all the manufacturer's specifications for your engine and provides the ultimate lubrication compared to a standard petroleum based oil. Be happy. Your good to go.
I think of it like this - - Smirnoff makes regular vodka right? Belvedere makes 'super' vodka. BOTH kinds get me totally wasted, but Belvedere tastes better. How deep are your pockets?
It does do everything that it says that it does. Think about it like this. Normal oil is good, with small particles. Synthetic is better, whit smaller particles. Purple is the best and has the smallest particles. This means your friction is going to be less because more surface area is lubricated. And because there is less friction, you car is going to perform better (MPG, HP, ect...). I hope this helps-Matt
A lot of racers use it and mobil 1, I'm sure they know something about performance.
We use to use it for our 300z .. great improvment!

Is it to early to change over to synthetic oil?

I have a 05 Pontiac G6 with 40K miles on it. Is this to early to change over to synthetic oil? What synthetic oil is best and what filter should be used? List a few types please. Thanks!Is it to early to change over to synthetic oil?
you can change it whenever you want to but i recommend you run 3 or 4 times with semi-synthetic because if you switch over to full synthetic it could damage your engine as for types of oil, i say Mobil 1.Is it to early to change over to synthetic oil?
No, it is not too early.





In fact you could have used it from day one. Modern engines are machined with such great accuracy and to such tight tolerances that break-in is pretty much a thing of the past. As a matter of fact, GM is now delivering all their high-end cars with Mobil 1 from the factory. The reason they don't in their less expensive cars is that owners are less willing to pay for the more expensive oil changes, the engines themselves can certainly benefit from synthetic in the same way as the engines in expensive cars can.





Hype notwithstanding, there is no good reason not to use oem oil filters. Most aftermarket filters (fram in particular) are cheaply made and not as efficient as oem. Try sawing one in half if you don't believe me: you'll be surprised...





As for oil: Mobil 1, Amsoil, Red Line, Lucas, Royal Purple. Watch out for Castrol Syntech, Pennzoil, Valvoline, Quaker State synthetics, etc.. they are good oils, but are not real synthetics in the sense that they are still highly refined dead dinosaurs, in fact they cannot be sold as ';synthetic'; outside North America.





By the way, it is absolutely untrue that synthetic oils don't mix with mineral oils. You can mix any modern synthetic with any mineral with no problems whatsoever. I don't know why people still believe that they can't...
no its never too early too change over to synthetic,if i was going to switch it though id go with mobil one full synthetic in it, its the best there is on the market right now and you don't have to flush one to change it either,it mixes well with conventional oils ,you could have changed that one over at 20 thousand not hurt anything,use a 10-w-30 in it though keep it as thin as possible for as long as possible,good luck.
I would make absolutely sure that you can use a complete synthetic oil in a gasoline engine.


I use Mobil 1 in my VW Diesel since it was new.


But, diesel engines are tighter and have a higher compression ratio than gas.


I would advise you to research this idea very thoroughly before attempting to switch over.


You could / can cause engine damage......
No, I believe that sounds like a good time to do it! Short and simple! Best kind are probably Mobil 1, Amsoil, or Royal Purple. Filter is a filter and Mobil 1 says to use theres with there oil but you realy don't need to.





Fram filters are JUNK! Buy a Wix, much better quality. I have seen a cut out of both and what a difference. If your Fram filter stops filtering, the motor will still try to pump oil through the filter whereas Wix would by pass the filter until its changed.
You can switch to the synthetic anytime and it won't hurt a thing, mobil 1 and royal purple are two of the best synthetics but all synthetics are good and you can't go wrong with them, you can use any type filter you like as you don't have to use a special filter with synthetic.
No its not to early I actually would suggest it. I suggest going with Valvoline full synthetic it tested better than mobil 1 but either are pretty good oil. You can go with a mobil 1 oil filter or if they make them for that model K%26amp;N filter.
The type of oil needed depends on what your engine calls for. It's never too late to change to synthetic. Synthetic is the best!! Mobil1 has got to best the best in my standards though.
No... there aint nothing wrong with using synthetic oil. as long as you use the weight oil your car calls for. your car proble calls for 5w 10 or 5w 20
it never to early the one i run is mobil 1 full synthetic and a fram oil filter
Mobil 1 and you can use it from day one.
I switched over our small SUV to full synthetic at 40K, no problems.

Ok, so I've decided to switch to synthetic oil, do I use the same viscosity as petroleum based oils?

I have a 2000 Sportster, based on the owner's manual it looks like cooler fall and spring riding I need 10W-40 and 20W-50 for summer, does this seem right?


What weight gear oil should I be using?Ok, so I've decided to switch to synthetic oil, do I use the same viscosity as petroleum based oils?
You want to stick with 20/50 (MAKE SURE IT IS FOR V-TWIN MOTORCYCLES....NOT AUTOMOTIVE OIL!!!!)......you can also run the same oil the primary/trans.





Here is an answer to a similar question...although it is in reefernce to a Big Twin.....the concept is the same though.....





As much I love HD....I hate to say it, but HD doesn't know SH*T about synthetic oil. For decades, they said not to run synthetic in their engines.....because of popular demand by the public, HD finally came out with their SYN3 synthetic oil several years ago, but it is honestly not worth a crap. THE BEST 3 SYNTHETICS FOR A HARLEY ARE


#1-AMSOIL, #2-LUCAS, #3-MOBIL1(which is recommended by S%26amp;S). I have been working on HD's and building performance engines, drag racing and dyno tuning for 20 years and have been running Amsoil for years, but have recently switched over to Lucas because it is just as good, but a little cheaper. AND THEY DO NOT AND WILL NOT VOID YOUR WARRANTY


FIRST OFF.........DO NOT RUN HD SYN3.....IT'S JUNK.........I AM A CERTIFIED HD TECH, AND I WILL TELL YOU FIRST HAND....HD DOESN'T KNOW JACK ABOUT OILS!!!!!!!!!


For deacdes, HD said to never run synthetic in their engines, their reason....it will cause the bearings to ';skate';.........but ask anyone on the drag strip running a top fuel 800+ HP engine what they run.......FULL SYNTHETIC.......their bearings don't skate!!!


By popular demand of the public, HD finally released their SYN3 back in the early 2000's......manufactured by Sunoco. SO........


Second......why would you WANT to go longer between oil changes?......esprcially on an Ultra, the baggers are subjected to to more engine strain than the other models due to their weight, plus they run hotter from not as much aie flow, that's why they have a larger oil tank to aid in cooling. FRESH OIL IS CHEAP INSURANCE AGAINST ENGINE FAILURE. Standard oil you should change every 2500 miles. You CAN go about 3500 on synthetic, but why? Scheduled PREVENTATIVE MAINTENANCE set by the factory are based every 2500 miles, IT IS BEST TO CHANGE YOUR OIL EVERY 2500 MILES....SYN or STD. Keeping up on the maintenace, prevents major breakdowns. It's btter to spend $400 or so a couple times a year than spend a few thousand to repair something that was caused by lack of maintenance.


As the other guys have said, synthetic does make your engine run cooler and lubricates much better than standard oil.


The best synthetic to run is 1) AMSOIL or LUCAS 2) Mobil 1


It is ok to run the same synthetic in the primary as you do the engine.......but NEVER use that same oil in the trans. HD says you can, but it makes the trans hard to shift and noisy......run minimum 75/90 gear oil......best if its 85/140......the absolute hands down best trans oil on the market is RED LINE full synthetic Shockproof 85/140...it will make your trans runs smoother, quiter and shift easier.Ok, so I've decided to switch to synthetic oil, do I use the same viscosity as petroleum based oils?
this is the oil you need good luck http://www.caracheosyntheticoil.com/inde鈥?/a>

General rule of thumb is NEVER use thicker viscosity than what's recommended. You can always go thinner on the cold side though, like a 5w40 or 10w50.
Use the same grade for mineral, semi-synthetic and synthetic as the handbook says.
well i use full synthetic and i use 0w 30 ts looks like water pretty much but i get about 8000 miles out of an oil change check out amzoil its a really good oil

Will synthetic oil make a difference in my 2003 mustang gt?

It's time to change the oil, and I'm wondering if I should use synthetic? Also, ford says to use 5w20 weight oil... Can I put anything different like 10w30 without hurting the engine?Will synthetic oil make a difference in my 2003 mustang gt?
Use the 5W20, it's common knowledge that it's more than up to the task when it comes to engine protection, especially since most of engine wear occurs at engine start up, and thinner oil gets circulating faster than thicker oil. There's no reason to use 10w30.





Also using synthetic oil doesn't mean you get to extend OCI (oil change intervals). It just means that you're using a better than required product.Will synthetic oil make a difference in my 2003 mustang gt?
yes/no...synthetic is tougher better oil...but


1 cost more...if you r changing you oil evey 3K you are wasting the 7K protection syn oil gives so u may as well use GTX or other fine regular oil


2 5w 20 is too thin and the 20 wt not enough protection...ford factory uses it to squeeze oit every 1/10th of a mpg for fleet average [and with a new engine]


i like 10 w 40 castrol gtx synthetic and change at 5K
I know my brother always uses Royal Purple 5W20 Motor Oil in his 02 (http://www.brenspeed.com/1520.html) mustang from BrenSpeed.com because I always receive the shipment in the mail. He has been a mustang enthusiast since he was a little kid so I trust the products he uses in his car. He said he doesn't use synthetic because it costs more money.
you should be fine with changing over to synthetic although keep in mind if your just driving it with no problems then why change? also if you switch to a synthic oil and you've been using conventional there might be some issues with leaking.
  • say yes

    What is the best synthetic oil to use in a duramax diesel?

    AMSOIL





    (Check out link below for more info on this synthtic oil-Hope this helps :)What is the best synthetic oil to use in a duramax diesel?
    Pretty much anything you can find will do, diesels have the benefit of being very reliable, so you could use any oil and make the car last forever. Otherwise, i'd say amsoil is the best you could easily get, just gotta order it online and pay shipping.What is the best synthetic oil to use in a duramax diesel?
    The best oil is Rottela.
    ROTTELLA the best! made by Shell,They also make Castrol I've always used these my engines stay clean inside.
