engile oil, what do you run + additives

[sleepertruck72]

I broke mine in with Royal Purple break in oil, for oil changes I use Mobil1 10W-30 Synthethic. About every other oil change I add/substitute 1 qt. of Lucas Oil Additive. I dont know if its that good or not, but I drive my truck hard and it seems to lubricate well

That is a roller cam. You do not need any special additive like a flat tappet cam would require. If you are really concerned about it you can contact the cam manufacturer for their recommendation or try to get in touch with the shop that built the motor. I wouldn't spend much time on it though. Any quality oil will be fine.

thanks fro all the input guys... it did help alot.... oil is changed to rotella 15-40 and new filter. called the builder and he said I should be good to go by his account...he said they added a breakin oil when it left the shop and what ever the previous owner did after that with oil changes he can't say.... so I get his point.... but at least I am on the right track now
