VOA Napa "synthetic blend" 5w30............any thoughts

looks like any other gasoline rated 30 weight oil as they mentioned. Possibly Valvoline branded oil. I know Napa Diesel oil is Valvoline.

Looks like an ordinary SP oil. Napa is Valvoline with a different label.

The TBN is weak, but that's also due to the method they use. I would expect 5,000 miles to be a good interval.

The KV100 starts out on the low side of a 30 grade at 9.53 cSt (30 grade = 9.3 - 12.4 cSt) which isn't a bad thing, just worth noting. This oil will likely shear out of grade given the likelihood of a good bit of VII content and being right at the edge.

Read their comments, they don't even know what grade it is. They state that it could be 0W20, 5W20, or even 5W30. What is up with this company?

I understand your fustration... I share some of that too. However, it has a lot to do with the oil company being tested so there are 2 pieces to the puzzle.

When I send them a sample, I do not tell them what is is other than motor oil. I agree that the TBN is weak in comparision to others VOA, but TBN as I understand does not "diminish" at any specific rate, respective to its use. In other words, another whos TBN say started at 9, may be "diminished" to a 2 @ 5000mi, while this oil @ 5.5 starting may be at 1 @5000mi. I suppose the only way to see is a UOA at 3-5000 miles.

This is Napa "blueish" bottle, "synthetic blend" (whatever that means) : https://www.napaonline.com/en/p/NOL75050?impressionRank=1

Added to my VOA Database. It lines up pretty closely with PQIA's VOA of the same oil a little over 2 years ago.

You can’t do that.

Bingo.
Looks pretty much what I'd expect. It's a lower priced Valvoline oil with a pretty decent additive package - good Boron, Moly, Calcium, etc. Zinc I think is near max (IIRC 800 is max for zinc to protect cats?). I sometimes use Napa, and my car loves Valvoline, so use with confidence. I've noticed my car runs smoothest on Valvoline versus anything else, it removes a little shutter that exists using other oils. I know that's not scientific, but it is a data point observation.

 

[himemsys]

do what?

I think what @kschachn means is you can't compare oils to find the "better" one just by comparing VOAs. There's a lot more to oil that is not represented by a VOA.

I did a sample of that oil as well recently with Scheaffer Webscope. They show the V100 on the low side. Here’s mine

I also sent a sample of Valvoline white bottle to compare against this Napa to see if they really are that close to each other. I’ll post that here when it comes in.

 

[mpgo4th]

Here’s the Valvoline sample. I think this show that at least the base stock is different and that Napa blend is not just rebottled Valvoline.

aggreed

Napa blend is not just rebottled Valvoline.

napa is made by valvoline, but not valvoline, agreed, but yet EVERY napa guy say this like it is the bible
