  • Best general use oil for 3.8?

    What is the best oil brand/make to buy for a 3.8L engine? Should I go with synthetic or regular? Thanks.

    Doesn't really make much of a difference what brand you get. People tend to stick with what they like best. Personally, I use Mobil 1.

    As for synthetic/dino, how many miles do you have? Switching to synthetic on a high-mileage engine can actually cause it to leak.

        Thanks guys. My car has 104,000 miles. Is that a little high to switch to synthetic? I'll take a look at the link provided though.

          I tend to use Valvoline Maxlife 5W-30 in mine. Its a semisynthetic that works very well, and is a slightly heavy 30wt. Definitely checkout bobistheoilguy.com if you're interested in oil.

              Probably 98Camaro3.8 is right. I started using full synthetic after 50,000 m. When my car had 65,000 it started leaking oil in the real seal, gaskets and other seal stuff. See that just I like to drive fast, but don't like to race. Damn! that cost me almost $1000 for the dealer to fix it.

                I've been using royal purple 10w30 since about 50,000 miles and I haven't had any problems or leaks. You should probably do an oil sample to see if you have anything in there that could cause problems later on. www.blackstone-labs.com

                  At the end of Part Three, we changed the valvetrain of the 3.8-liter V6 in the Tom Henry RS. We installed new, Yella Terra "Ultralite" 1.8:1, aluminum roller rocker arms, Katech valve springs and Katech titanium retainers on our 3800 Series II V6.
                  Ultralites are nearly 25% lighter than the stock 1.6 rockers and 8% lighter than the SLP aluminum...
