ahhh **** you're right, i knew i forgot some detail. I would rather pay the extra then and stick with the good stuff. yeah, it's more expensive but not a big deal. Do you think doing every 5k miles is plenty? I feel like changing it out before that is overkill for such a crazy good combo on the RL 5w30 and RP 20-820.
s'ok - that's why we have a Forum.
There is not a complete consensus on OCI for Hemi engines on the Forum. There is general agreement the engine has a lubrication deficiency, hence recommended super oils to help keep them together.
My view is 5,000 mile max. oil change interval, regardless of oil used.
It's not because the oil needs changing - it's because the engine can't tolerate contamination in the oil. This engine has marginal oiling, and small oil orifices in the MDS and VVT hydraulic ports. The oiling to the lifter rollers is also poor.
Anything contributing to poor oiling of this overly sensitive engine should be mitigated to minimize risk of losing the lifters and cams.
A good idea is to increase idle rpm, if you get a tuning software.
