I run Castrol GTX 20-50w. If I were to switch I'd probably go with Mobil 1. But the Castrol is doing just fine.

I run 15w30 mobil 1.

They dont make a Mobil 1 15W-30..?

you're funny

No seriously, they dont. Do you mean 15W-50?


But anyways, they sell Mobil 1 in 5 quart jugs at Wal-Mart for like 19 bucks. Thats where I go to get my 15W-50.

I use 0W 30 Amsoil series 2000 synthetic oil. I have just a small oil seapage on the front of the engine. Extra protection when the engine is cold and protects like none other.

Every car on this message board should be using 15-50 or 20-50.

The only exception is during really cold winters; then you may step down to 10-40 or 10-30 even. No less.

all the "hot-rod and import guys" jump on this stuff as soon as my local auto parts stores get it in. We have a hard time finding the 20-50. Im all about the havoline 10-40 for the most part. With as many miles as I have it is redundant to switch to synthetic. It is good, but it better to start when your motor has like 35-45k on it. Any of your guys remember the rondell artical on the million mile 325is? Exxon Mobile grabbed a bimmer to do a million mile test using fully synthetic fluids and they broke the barrier no problem.
