The NASIOC Oil Selection Guide

[Riz98]

Not sure if anybody on here follows or has read 540Rat's oil listings. Just curious if anyone has tried his new #1 which is Quaker State 5w30 Full Synthetic. Kind of bummed that Castrol 0w40 was pretty low on his list for wear protection. I usually run Motul Xcess 5w40 but going through a quart every 1,200-1,600 miles gets pricey when Walmart has decent oil. The newer Mobile Euro FS 0w40 had good results. I am not sure how much extra oil I'll be consuming switching to a 5w30 but I might try the Quaker State this go around unless anybody advises against it

540Rat's oil listings are for entertainment purposes only. He likely uses a Timken machine from 1935 which was designed to test EP additives in greases and gear oil which have no bearing on how oil performs inside of an engine.

There may be very minor differences among oils that meet the same specs, but today's oils are all very similar so pick your favorite brand because you'll never know the difference. Like the Motul X-cess that you run, Castrol Edge 0W-40 meets Porsche A40 and MB229.3/229.5 specs which are the toughest specs in the industry.

Quaker State is owned by Shell and uses the same base stocks as Pennzoil (GTL) so it's a good bang for the buck oil. Mobil 1 has started using GTL base stocks as well. Given that you have a 2008 FXT, I'd stick with a thicker oil like QS 5W-40 or Euro XW-30 if you want to try QS. I wouldn't run the standard API SP/ILSAC GF6 oil in an EJ.

Again, compare oils that meet the same specs. Not what some clown with a machine from 1935 says.

Does Royal Purple fall anywhere on this list as a good recommendation?

Sort of. HPS has an old school high ZDDP additive pack with their Synerlec additive. Although If you have a DIT then I would not recommend it.

Their certified line isn’t anything special after Calumet took over.

Virgin oil pr0n.
This stuff has higher zddp and molly bedunum than i have ever seen. About double zddp from motul 300v and 200 higher moly ppm.

Has low detergents and relatively low TBN. Short interval for sure (6 mos 3k max for sure). Detergents have been implicated in detonation so im good with that.



More expensive than columbian puro though.
