I don't ask for much, just A3/B4 and the fatter the additive package the better.
I just ask the voices in my head for their consensusFrom what I have gathered here, I have found choosing oil is quite simple:
Find the most affordable oil which meets manufacture's specifications/approvals.

Noack can show you how equal the base molecule size is for a given viscosity. But there is a band for that viscosity class and that can be wide. Generally hydrocracked crude oil is higher. PAO has to be mixed with other base oil and can include hydrocracked base with POE for it to work correctly. The TBN is the starting basic number of the detergent portion of the add package. Kirkland shows 2.75 HTHSI have a question, if you look at the oil I'm using, the Noack percentage is 9.5 if you look at Castrol Edge it is 8.8 if you look at Mobil 1 it's 8.1, which is even lower which is better what I understand.. why is the Noack so high.. the viscosity we are talking about is 5W20..
I have one for each of my criteriaI just ask the voices in my head for their consensus
So if it's lower is that a better thing, yes correct? POE is better I guess?Noack can show you how equal the base molecule size is for a given viscosity. But there is a band for that viscosity class.

No, it's the kind with sprinkles on top!The absolute best oil is a 0w-xx with a plant derived base oil.
Let's just drop it!!!!!No, it's the kind with sprinkles on top!
Again, to the OP, you have to define "Better." That's a very subjective yard stick. If everyone was honest around here, everyone would answer, "Heck if I know."
Given the reproducibility of the test method, all three of these results are considered equal. Throw in batch-to-batch variations and you are splitting hairs.I have a question, if you look at the oil I'm using, the Noack percentage is 9.5 if you look at Castrol Edge it is 8.8 if you look at Mobil 1 it's 8.1, which is even lower which is better what I understand.. why is the Noack so high.. the viscosity we are talking about is 5W20..
So Mobil, Castrol and QS are Equal?Given the reproducibility of the test method, all three of these results are considered equal. Throw in batch-to-batch variations and you are splitting hairs.
No.So Mobil, Castrol and QS are Equal?
If superior base oils and additives are what you are looking for, AND the oil needs to be easily attainable I'd be looking into extended drain oils. For the manufacturer to say their oil is good for 20K / 1 year over many different applications they are likely using higher quality base oils, better / more additives or both. M1 EP comes to mind.I've already done that.. I'm running the oil.. but what I'm trying to do is, I know there is a better oil out there, and I'm trying to figure out how to find out what that better oil is. All the oils, on the shelves for the most part, is going to have, GF-6A SP Rating.. and as long as it has the licenses for my particular vehicle I know I'm good to go.. I was just looking for a better oil.. and I was trying to figure out how to find that?
