The biggest issue is using convemtional or a dexos approvend blend. After breakin, get a good full syn in and never use a conventioanl. It is a sure recipe for failure (I know of no one doing more with the LLT & LFX engines than RX). Any one that should know better and still uses conventional is just asking for failure.

And yes, the new chains are improved, but not by alot. It is also critical that you check oil levels regularly as these do NOT have low oil indicators, so you need to monitor it every few fuel fuel ups.

Looks like I might be switching to Syntech . . . I've actually heard bad things about the Penzoil, though?
