What Is Your Preferred Oil?

Shell Rotella 15w40 regular (or synthetic blend) - one trip halfway across the US and 1000 more miles, never lost a drop. Cons: diesel like chatter from the heavier oil (not actually a problem).

Penzoil regular "conventional" oil (not synthetic) is the only oil I will ever use. Unless it's a brand spanking new car with super low miles, I would never use synthetic oil.

On engines with a decent amount of miles, the varnish build-up deposits of conventional oil actually helps "seal" the engine between the seams of various components and helps prevent oil leakage. Sometimes switching from "conventional" to "synthetic" can cause more harm than good as it removes the varnish build-up deposits that help seal the engine, thereby causing oil leaks.

Just ask VX member "HYPERKID" who switched from conventional to synthetic in his VX and it caused major oil leaks. His VX eventually leaked oil out of various engine seams at an excellerated rate and his engine fried due to lack of oil. He had to replace his VX engine for $$$. Before he switched, his VX ran fine on normal conventional oil with never a problem or leak. Lesson learned.

Plus, conventional oil is way more inexpensive than synthetic!!!

Thank you all for the opinions.

I have 27K. Does that affect your opinion?

Also...

I am going to use an additive called Xcel plus:

I put this in my Celica AllTrac 100K miles ago and my milage increased and I've had NO engine or turbo problems at all. Many AllTrac owners cannot make that statement.

I'm a believer!

Nope, way too many miles on yours for sure. I'm stickin' with normal regular "conventional" motor oil. It's more cost effective and does the same job without the fear of causing more harm than good. Like my Dad used to say-- "If it ain't broke, don't fix it!!!"

Thanks RR... I'm going with your advice!

I guess we should all still be riding horses then!

By the way...I switched from conventional oil to mobil1 at 70,000miles. 70,000 miles later no leaks and running strong.
Also burn zero oil between changes!

Who is more reliable on oil suggestions? The guy who uses 1-2 or the person who tries a new oil every time they change it? Frankly I do not think you can reliably judge an oil you use for just one cycle of oil.
