Seeing that PQIA hasn't published any recent NOACK results for some oils lately has me wondering. I hear Valvoline Synthetic and Quaker State Ultimate Durability are low NOACK. Even Super Tech is; is Pennzoil Conventional or Quaker State Advanced Durability?

Thanks
 
Valvoline posts the Noack on there website PI sheets. I just looked up the Valvoline synthetic motorcycle oil a couple of weeks ago and the 20w50 was 4.
 
Mobil 1 High Mileage 10w30 has a NOACK of 7.6%.

The boutique oils like Amsoil, Red Line, and Driven tend to have very low NOACKs at <7%.

It's not really clear what you're asking. You note that PQIA doesn't give this info recently; we have known for a long time herr that nor does that vendor...

Then you're asking folks on here to effectively speculate on this... without even giving an objective standard for "low", and then you complain about quality of content on here?!?

Pot, meet kettle.

Yeah, I'm used to being blamed. I ask what the NOACK is on some oils. Guess I cannot ask a simple question anymore without being called a name like post above yours.

PimTac: yeah that was real low
 
IIRC the Noack loss for MAG 1 5W30 synthetic is 12% and Super Tech 5W30 synthetic has the same dexos 1 Gen 2 license # and blender...that's good enough for dexos 1 Gen 2, but I wouldn't call that a low Noack loss.

AMSOIL Signature Series 5w30 and Ravenol DXG 5W30 are both pretty outstanding for this test, the latter is 6% and the Amsoil is 6.7% per the manufacturers.

I'm so glad I don't post much anymore here. I ask a question and get flame roasted. I won't ever ask a question if I'm going to be treated like a idiot. We are here to learn and discuss


Have a nice weekend

Well, I was going to ask that and forgot about it. I guess we wont ever know which "current Api sn and sn+ oils NOACK are.

Oh well I just dont care anymore and wont
 
I think typical api limit is %15

looking at different specs. the lowest I've ever seen is %4.1 for AMSOIL Signature Series 10w30

anything in the %6 or %7 range and lower in more expensive oil.
some good oils are %8-9 range
least expensive oils, expect %12 +/-

And the info sir

IIRC there was a time when the PQIA measured Pennzoil Conventional 10w30 at something like a 4.4% Noack loss...they couldn't believe it either and retested with something like a 4.2% result!
BITOG was on fire with guesses as to what was going on...then a new result came in a over 10% as one might expect from a conventional quite some time later.

See, I asked about PQIA and they used to test for NOACK and now they dont. And we all know they never said why either


Thanks sir for the info also

There was some discussion a while back about difficulty in determining the NOACK. The numbers would vary widely from test to test or something of that sort.

I cannot remember if that was answered or not.
