- Change @ 41k was Amsoil Signature Synthentic with 19k miles on oil
- Change @ 126k was Super Tech Synthetic with 10,855 miles on oil
Yeah, OE is probably like a more expensive M1. For the price I'd just use M1.Thanks for the uoa. Not bad considering it's in a gdi TT. I've heard of amsoil OE being 100% group 3 without any group 4 and i still don't know if it's true. But it does seem good. I wonder how Pennzoil platinum euro L 5w-30 would fare.
That's for Signature Series and why would anyone buy single quart bottles when it's available in gallon jugs which would be a little cheaper. Also, we're talking about OE here which is around $33 /gallon. I know it's about $10 more vs PP but some guys just want the Amsoil for some reason or other.$14 per qrt. equates to $70 for 5 qrts. which is what my vehicle requires. Or $22 for Penn Platinum and with regular OCI and a good filter, Amsoil is probably good, but it sure ain't 3.5x better.
It would be nice is we could find an unbiases source of information on the [I am not sure of the proper wording] the film strength of the different base stocks and blends .Thanks for the uoa.

Maybe you could try Amsoil SS 5w30 if you're doing 30k a year. 15k mile oci x 2 with Fram Ultra filters for each oci.Thanks for sharing. I haven't done the research on the Group 3 / Group 4 stuff you mentioned. I ran the Amsoil Signature to nearly 20k miles. The filter looked like it was in a turbo truck in Florida for 20k miles. I figured if I went 10k miles, that's less dirt in the motor and just not pushing it so far - but could I do it with a lower cost oil? I tried the Super Tech Synthetic and Amsoil OE and went to 10k with Super Tech and 12k with Amsoil (not on purpose). It seems like both are good options for 10k OCI and the price is right on both. I drive ~30k miles per year so expensive oil is going to cost a few bucks, but whether I think it's worth it is something I have to consider. Besides, who doesn't like the idea of finding something that works great for a great price?
Even if that's the case, it means absolutely nothing. Different chemistries will have different signatures and spectrography has no way of discerning metal that's been chelated through chemical process from actual physical wear.I partially agree but vanilla M1 usually spits
out higher iron numbers than this OE sample or most others for that matter.
You can think not all you want.I think not. OE would be like regular Mobil 1, Castrol Edge black bottle, Valvoline Syn Power or Pennzoil Platinum. Mobil Super Syn is basically a blend as far as I know.
You are mistaken.OE has a tbn of 8, XL 10, and SS 12. Don't believe me ask Pablo. OE is equal to all of Walmart's brand name regular shelf oils. XL is obviously a bit of a niche because of it's higher tbn= 10.You can think not all you want.
AMSOIL used to only have the two categories, their Group III product, XL, and their premium extended drain oil, SS.
Now, they have three, with a cheaper entry-level product in OE. So, if we were doing a comparison with Mobil, the products would slot as:
OE - Mobil Super Synthetic (Group 3, designed for normal drain intervals, price conscious, Mobil says 7,500 miles or the OE interval, AMSOIL just says OE interval)
XL - Mobil 1 (Mostly Group 3, some PAO, longer drain capable, more costly, Mobil also uses AN's and POE, no idea if AMSOIL does at this price point. AMSOIL says 12,000 miles, Mobil says 10,000 miles)
SS - Mobil 1 EP (More PAO, AN's and esters. Extended drain capable, most costly. AMSOIL says 25,000 miles, Mobil says 20,000 miles)
I'm not mistaken.You are mistaken.OE has a tbn of 8, XL 10, and SS 12. Don't believe me ask Pablo. OE is equal to all of Walmart's brand name regular shelf oils. XL is obviously a bit of a niche because of it's higher tbn= 10.
Yes, it's recommended for up to 10,000 miles, we've already been over this. XL is recommended for 12,000 miles.OE recommends olm, do you think vanilla Mobil1 is recommended past the olm?
You have to watch both TAN and TBN. But different chemistry can have them cross while the oil is still serviceable because certain chemistries can skew TAN.Usually tbn will dictate oci.
Yes, you can. TBN depletion isn't linear and two oils with the same TBN will not necessarily deplete at the same rate. You have to run them both in service to see how they ultimately hold up. TBN depletion also isn't the only factor. Fuel dilution, oxidation, contaminant uptake, these are all factors that can result in the termination of the OCI before TBN is depleted.With a tbn of less than 8 you can't compare vanilla M1 to Amsoil XL.
Yes, so does Mobil Super Syn.OE lets you go as far as mfg.says or olm.
Yes, and that's the same provision for ANY of the off-the-shelf oils. They are suitable for use as long as the OE interval, dictated by the OLM. That's part of the bloody approval process! The point is that OE is only guaranteed for that usage profile, while XL steps it up to 12,000 miles if that exceeds the OE interval. Mobil 1 is similar, it steps it up to 10,000 miles. And of course we still aren't discussing M1 EP with its 20,000 mile interval, are we?That could be anywhere from say 5-12k miles depending on usage and algorithm.
Dude, I'M A DEALER!, did you read my bloody post you responded to? I've known Pablo for FOURTEEN YEARS on here. You aren't going to win this argument, full-stop.Go to the website, call Amsoil or pm Pablo. Vanilla M1, please.
