20,000 mileKind of a low TBN for their “advanced“ oil, no? Isn’t that the 15,000 mile oil by them?
Supertech Regular syn 0w20 is 7.1 according to what someone else posted just a little while ago! Wild that this has a lower TBN than something rated for 10k by the manufacturer. EDIT: sorry, im an idiot. The other sample was also of the advanced 20k ST. Sorry!I've been waiting for this.
See no reason to run this over the regular syn. As pointed out low TBN, notcsure what the regular syn numbers are
What’s your thoughts on it, would you use it for extended drains?20,000 mile
What TBN value is necessary ? Who's to say that the decrease/drop in TBN in linear over miles ? Maybe it maintains TBN in the ~7 range for many miles at the start before it starts dropping.Kind of a low TBN for their “advanced“ oil, no? Isn’t that the 15,000 mile oil by them?

For a 20,000 mile oil? I don’t know, but I imagine most 15,000 extended performance oils start out with something higher than 6.9, no?What TBN value is necessary ?

I've never gone past 5k. So if I owned something that was easy on oil, I'd probably extend to 10k.What’s your thoughts on it, would you use it for extended drains?

But you might be right, it may remain linear through the interval.
mobil 1 0w40So I assume it is mostly safe to say this oil does not have any grp IV stock in it, or at least to a meaningful degree? What would prevent this oil from shearing down too much in 20K miles? It will be interesting to see how the UOA turns out for this oil at 10K+. I have an engine that comes with oil-shearing Ginsu knives in it, for the sole purpose of destroying oil... so, thinking of going with the 15-20K oils for hopefully slightly better oil longevity.
I know M1 has excellent long drain oils, but if I can use Super Tech for a lot cheaper I might give it a go. On the other hand, if I could extend my OCI, I could possibly go a whole year with only two oil changes and go with M1 5w-30 EP using their rebate, which would end up around the same price as Super Tech Advanced.mobil 1 0w40
if it’s DI go with a C3 oil
