Lowest Viscosity Index 10w30

[Japanese]

I’ve never seen “cleanliness” in API Annex E but no doubt it appears in some form in many licenses or approvals.

Well, it's part of ILSAC. All conventional and synth blend oils today cover ILSAC GF-6 and GF-7, right?

I don't believe these types of graphs but here it is:

Yes, those are areas of emphasis between iterations and not any sort of quantitative values.

I'd say ESP 0w-30 has a 99% chance of outperforming all 10w-30's off the same walmart shelf in shear resistance and noack even though it's a 0w. It has much better polymers and a base that can naturally require less polymers at the beginning.

Does it resist viscosity breakdown better than a good 10W30?

ESP 0w-30 has proven itself to be very shear stable

Is it as good as a good 10W-30 in that regard?

Absolutely

I meant within the synthetic oils and I meant viscosity index. Trying to see if 10w30's VI can shed some light on base oil and how much VII would be present.

Here are two 10w30s that meet API FA-4. The Delvac offering also meets SN.

PC Duron Advance 10w30
40C 66.2
100C 10.3
HTHS 3.1
Vi 143

Delvac Super FE 10w30
40C 64.1
100C 9.8
HTHS 3.1
Vi 140

I never would have guessed that. I guess a person has to change his own oil or go to the dealership for something like ESP 0W30.

What do they charge for an oil change using that oil at the dealership for your car?

I’ve never heard of any dealerships that would use ESP. You would have to buy it yourself and bring it to them, or just DIY.

Recall what the dealership charges for an oil change using whatever oil they use?

I've put 165k miles on the supposedly fussy and dirty Mercedes OM642 V6 Diesel with 5W-30 ESP and now I use the 0W-30 ESP oil. You don't have to worry if it's 'good" at all or if it is suitable for either Diesel or Gas burner.

You’ll have to check with the dealership in your area. Prices are going to vary a lot.
