What oil do you use in your MC?

[mts205]

Used mobil one 15w50 full synthetic yesterday, jug says it has extra zinc for "high performance engines" plus it was 13$ for a 5 qt jug at walmart, I'm still happy about that deal!

Rotella in the Boat, Mobil 1 in the cars.

Exactly what I do. Can't go wrong there.

Valvoline premium blue 15w40. It was rated as the best non synthetic oil and one of the best overall in a diesel oil study.

Rotella T-6. I have read nothing but good things about it on BITOG so I use it in my small 4-stroke engines, my chevy 1500 in the summer, and in the boat.

[csherbo]

^^^ This is correct - I use Mobile 1 - 5W30 full synthetic

Here is where you can get an electronic copy of the Ilmor Manuals

No foggy just reading the manuals and know my oils

[SamS&S85]

Would there be any harm in taking your old filter out and bringing it to NAPA? If your going to change your oil anyways, its an easy way to figure out what you have

[Cc4me]

So I don't see the filter model listed anywhere in my Ilmor manual or on the mastercraft site. Does anyone have the ilmor 5.7 liter filter model?

[Tsumi]

Amsoil 15-40.

Rotella in the Boat, Mobil 1 in the cars.

[Nick911]

I use whatever the dealer puts in it when they change the oil. Bam!
