Years ago here, the rage was that Dino Syns (Valvoline and a few others) in GroupIII wasn't really a syn, it was just severely hydrocracked cracked Dino and many folks were really angry that they were allowed to be called "Synthetic". I also remember folks returning the same OA results from the GroupII High-Moly Havoline as the "GroupIII" Hydro-Cracked "Synthetics" from Castro and Valvoline. Group 4 was something else again (M-1 before they went GroupIII Dino, admitted only under great duress by the folks here if I recall). Group 5 base oils were to be the holy grail, gas-to-liquid pure base stocks. Now they're erasing the GroupIII and III+ as if it never even happened? Ah well. Interesting reads. The ebb and flow of opinion, UOA and gobbledygook from the oil companies makes your head spin if you watch and read. It's all good.
As for extended drains, they make VERY clear that Shell doesn't set drain intervals. We as owners do that per the manufacturer and of course, our own whims. Clean? Not sure how we're to tell without dismantling the engine. I suppose if the varnish disappears from the dipstick and also whatever varnish you can see from the fill-hole, the Ultra, absent a tear down, is an engine scrubber.
Meanwhile, the miracle of gas-to-liquid finally came to pass. Use with confidence, as they say. Except I probably won't bother with my 2004 2.5 Subaru 4, because in the end, a Wix and 7500 mile drain intervals on dino is honestly, good enough.
Anyone have a case of Dino Havoline 5W-20 in SL or SM in their stash they wanna sell?
So Mobil-1 is now group 3 then what is the best on the market these days ? Is the Platinum extra the best on the market now ?
Best.
Tough to say.
Firstly that guy up there is clueless. Since Mobil doesn't tell anyone the percentage of pao/ester and hydro cracked basestock in their formulas no one here has any real data saying one way or the other.
Mobil uses what's called "visom" and it's a mixture of various basestocks. We've seen posted here at BITOG that AFE could be as high as 30% pao and the EP line is even more concentrated.
As many here know I'm not an m1 fan at all but that doesn't mean they don't make a great product.
So sir to answer your question about best I would need to know how you drive,if cost of oil is a factor and what oci your after.
Because depending on how you answer "best" could be different.
I buy name brand syns on sale. That's "best" for me because I pay less than regular priced conventional and run a 10000 mile interval.
For my charger I thicken the oil load up with 0w-40 in the summer because I beat on it often.
So that's what best for me. Best overall would have to take in to consideration a persons variables,so what's best for me may not be best for you.
