It just seems like on paper/in theory it makes a lot of sense. They're notorious for beating American full synthetics out of grade, although Castrol and PP seem to hold up decent. Those oils probably have a HTHS of 3.1 - 3.2. I'd trade an mpg or 2 for some added protection/longevity, especially for the turbos and my 17ft long timing chain, especially in Florida's 9 month summer. Been a long time PP user and have 163k trouble free miles and in a Mazda 6 Skyactiv. Just starts out too thin for my taste in this particular application. I'm trying to avoid premature wear on that timing chain since it's not a cheap job on this truck.
I've seen a lot of folks talk about Mobil 1 and Castrol 0w40 but can't find any UOA's on them for my motor, maybe one UOA but there was a problem with the motor and was showing crazy high iron or copper, so it wasn't helpful. There are some other posts but the image of the UOA is gone so no data to look at. I'm sure the 0w40 gets beat to a thick 5w30 anyway, as has always been typical of those grades. My hesitation on running 40wt is I work 5 miles from home. So the truck see's short trips. I want oil flowing to the chain, phasers, and everywhere else as quickly as possible considering I may not get that oil up to temp as often as I'd like to. It sees the highway on the weekends to burn up fuel and I'm running a catch can which mainly traps oily gas. Been running Castrol Edge EP so far and it seems to slow down the fill up time on the catch can and run really smooth. I'm thinking maybe some of they're claims of the high temp stability are true. UOA will be coming after this OCI is finished, 5k to set a baseline. Want to know if I've found my long term choice and can stock up or if a Euro oil is a better match for this application.
So very curious to see how the Euro 5w30 holds up as a thick 30 to the 3.5 EB oil beatdown. If any of you can point me in the direction to see some UOA's of of euro oil in this motor, I'd greatly appreciate it. If no links available, I'll try it out myself after I get through some Castrol EP and Valvoline EP sitting in my garage. Will definitely be doing UOA's on those, especially the new Valvoline as there aren't many out there yet.
