synthetic oil My car has about 65,000 miles on it and I have always used regular oil when changing at every 3,000 miles. I usually use up to 1-1.5 qts. Can you change to synthetic oil after running the car this long on regular oil? Will it help or hurt anything or just drain my wallet?

i reccomend a thicker synthetic. Usually when you switch to a synthetic, your oil consumption should drop, since the synthetic oils have a higher flash point that dyno oils. I reccomend Mobil 1 0w-40. I love it, protects great at ALL temps, and is a good think oil, yet flows as well any!

I googled synthetic oil and this proffesor said to explain
it to the layman if you take a quart of regular oil in the winter
and pour it. It will pour like mollasses while the synthetic will
pour like it's a summer day.It's all in the viscosity.

you'll be fine switching now. But like others are saying go to a slightly higher viscosity The Mobil 0-40 is Ok and easy to find. Lots have spoken about the German made Castrol but it's harder to find

Go ahead and go to the synthetic if your wanting to. If your looking for a good oil that is readily available then go with the Mobil 1 5w40 truck/suv formula. Patman said it is the preferred viscosity out of the Mobils, where the 0w40 european formula "used" to be...I am going with the 5w40 on my next change.

ok...so I be slow now, so be nice to me. I went to the autozone.com site to look and see if they have the german castrol syntec and they don't even have a listing for 0w30 oil. They have an HD30 but it is not synthetic from what I can tell. Is the HD30 the same as 0w30?
