How many miles for oil change with synthetic oil?

can you go further between changes than with conventional?How many miles for oil change with synthetic oil?
The big benefit of synthetic oil over conventional oils is that it does not break down as easily or as fast. However, engine oil will still become contaminated over time as you drive. It's those impurities that you do have to get rid of by changing the oil.


Can you stretch oil change intervals? The only real way of finding out is by having your old oil analyzed.How many miles for oil change with synthetic oil?
15000 is fine
For what it costs I change it less often.
Synth you can go 5000, I've done it before but only with Mobil 1 - that is the only synth I trust for that long. Depends on the nature of how you daily drive -
My uncle's merdecez benz says every 12,000 miles, it's kind of crazy and hard to believe. The first oil change was at 16,000 miles...lol...not for me 5,500 max. using synthetic oil lol
10,000 minimum according to gregs japaneese auto. The reason is because you need to work in the engine and that has to be done with standard oil.





You can just do a drain flush and put in a stanard oil, but use one that is designed for high milleage. Then you can go until you reach 10,000. Do not go 10,000 without a high milleage oil or it'll break down to easily and not lubricate the engine properly.





Also, you should change the synthetic oil as much as you do standard oil. Not needed in many cases because you can get 3,000 miles extra out of it, but it does help keep the oil fresh and clean.
yes you can go further... a few thousand miles more.. instead of changing at 3,000 miles, you can change at 5,000 miles, but if those miles were made in city driving , you should still change the oil at 3,000 miles...





I change mine at 8,000 kilometers = 5,000 miles
I would (and do) change every 3000 regardless. Don't take chances with your engine.
I have a friend who uses synthetic motor oil in his truck, and he changes the filter every 3,000 miles but changes the oil and filter every 6,000 miles. He hasn't had a problem (his truck has over 150,000 miles on it and runs fine).





P.S.: Be sure to top off the oil if you change the filter only. Shouldn't take more than a quart if you do that.
depends on how you drive...





my caddy has an oil life meter, it takes readings on engine conditions and subtracts percentages accordingly, when it gets ';low'; 10% oil life or less, i get around to changing it, it has gone anywhere from 1000 miles (once when i overheated) to 7,000





and i always use mobil 1 full synth
