What engine oil do you use?

Torco SR1 ... Great stuff and still has all the additives that are missing in many (most) oils.

Mobil 1 full synthetic - use it in my racecar, street car and collector car. I've used it in my wifes Jeep since brand new, change it every 6000 miles - she now has 148,000 miles and it still looks fresh at each oil change.

Delo 400 15-40. It fits in my Cummins, my 2 440's and the lawnmowers.

The owner of Pure Power told me to run Delo 400 15-40 !! Said it has all the good stuff still in it... but to NOT run the LE (low emissions) as it has reduced levels of the good stuff (zinc and manganese etc).

I use his filters -- they filter 100% of your oil with a cleanable SS mesh filter... they're "expensive" --- but so are all the parts INSIDE my motors...LOL

The diesel grade oils are supposed to have more of the better additives than regular "gas" oils, although they are reduced from what they used to be.
