Engines are very rarely rough on VI improvers. Motorcycles where the transmission and engine oil is shared are. mPAO's are very good. They are also very shear stable. We do have a KRL in our lab and routinely use it to look at shear stability. This is of course only 1 part of the whole picture and with any motor oil we will run the whole battery of tests in the lab to be sure that we verify the requirements of SAE J300.
Generally speaking light oils (this needs to be defined since we make some extremely light oils) will use very little if any VI improver. Again based on the application will dictate which one I choose.
We do not cut corners on raw materials. In fact our lowest quality VI improver in our plant is a 24SSI material that is solubilized in a synthetic base stock.
If you have something specific you would like addressed I'd be happy to do so but for now at least you have some general information relevant to your question.
Thanks for getting in here, and your products are appreciated !
Are you touting the presence of VII's in your thin oils ?
Other boutique oils tout its absence.
I need a very thin oil that does not get too "cute."
TY.
Per my Signature, the vehicle in question is a 2019 Lexus UX 250h F-Sport, already at 50k miles.
It is spec'd for 0W16.
As a delivery driver-medical courier-subcontractor, the issues here are always MPG + durability. Valve seat wear, valve stem seal integrity, and piston ring coking at the high miles I quickly accrue are all on the front burner.
I am very impressed with Toyota's D-4S system. I examine and smell my dipstick often. There is no soot or fuel dilution here, gang. For me, warranty is no longer an issue.
I am also now very impressed with HPL products. To cut to the chase, I will now, based in large part upon your providing reassuring detail, seriously consider
HPL 0W20 as my High Mileage oil, and decision time will be soon.
