    Default engine and trans oil?

    I started running mobil 1 syn. oil a few years ago. Just wondering what everyone else uses. What do you think is good/bad. I gained noticeable power from changing the factory oil to syn.

    I've been running Mobil 1 in everything we have for at least 20 years and no problems. I use there engine oil, trans fluid, gear lube and grease.
