Hi, I use the Mobil 1 15w-50 from wal-mart but it doesn't say Extended performance. Might be a marketing change ? I put Mobil 1 75w-90 gear oil in the other hole. Runs cool, shifts great. Altho I do use the K & N chrome filter also.......WVleo
During an oil change, does anyone ever use the 4 quart change? Flushing out the engine with a quart of cheaper oil, maybe a light weight oil, before filling up? I wonder if this may help clean the engine a bit.

Hmm I just checked the Mobil site and it is different:
What is the difference between Mobil 1® Extended Performance and Mobil 1?
Mobil 1 Extended Performance formulas are designed specifically for today's longer service intervals and are guaranteed to protect for up to 15,000 miles or one year.
Mobil 1 Extended Performance has a unique formulation with a boosted level of protection and performance. Mobil 1 Extended Performance, with the Advanced SuperSyn System, contains 50 percent more SuperSyn than Mobil 1.
Last oil change I punched holes in the end of the filter at the top and bottom allowing a half hour for the oil to drain. A couple paper towels at the base when removing the filter and no mess at all. Personally, I think many full synthetic oils will work fine.
