Can you switch from synthetic oil to standard oil when you change a cars oil?

If you have been using synthetic oil, why switch to conventional oil at all??? All conventional oils will inevitably create sludgy deposits and will eventually require de-sludging treatments. You are much farther ahead by sticking with synthetic. Oil change intervals last longer and the protection at extremes of temperature is unsurpassed!!! Conventional oil gives off vapors that re-condense in places in your engine that cause trouble, eventually. Synthetic oils give off little to no vapors. Economically speaking, you end up saving money in the long run by continued use of synthetics. Oils do 2 things, lubricate and clean. Synthetic oils (mobil one or better) do these jobs best. Synthetic oils can prolong engine life by 2-3 times. Don't risk it!Can you switch from synthetic oil to standard oil when you change a cars oil?

Yes. Any SF/SG rated oil can be interchanged. Try not to mix them in each oil change unless you are already using the synthetic blends.
Yes, but if your car requires synthetic (some, like turbo cars, do), keep using synthetic. It will take a couple of oil changes to clear all the synthetic out of the system, but they are compatible.
no, simply no
yes, it won't hurt a thing, the only thing is if your car is older and uses or leaks oil it will use it faster with synthetic.
yes u can switch.
I agree with RobertM. we had a young lady who didn't know her car took synthetic and we used regular oil and it smoked terrible until we replaced the oil wit synthetic. so If you are using it now stay with it it could void any warrenties or recalls by dealerships for your car at anytime.
NO, if your car came with synthetic oil in it at new it obviously needs it ,putting standard oil in wont have the right mineral content to coat ur engine parts correctly,stick to synthetic
i agree with rotus
