I don’t have Pb in my system ever and asked for a re-do on Iron, aluminum and lead. The results are even lower. Wear metals are 1.32ppm/1 K mi
To the Valvoline team, thank u and I will be reducing my future UOA.
HPL Euro is a very different oil than Valvoline Restore and Protect and has more expensive base stock which shows up as higher oxidation and nitration values. Valvoline Restore and Protect is built on the cheaper Group 3+ base stock with Valvoline’s exclusive proprietary low wear additives.
I agree. It is my forever oil.
Sample #5 is VHM 5w-30, #4 is HPl euro is sample #3 + 5457mi, #3 is HPl euro 5w-30 with 4k on the oil. No oil consumption
As promised the results are in. I asked for the missing oxidation and nitration. In my case, the Valvoline Restore and Protect is a 5k OCI for the 2GR-FE. It is a Ho-Hum post. 1.75 ppm/ 1K mi wear metal rate.
With Valvoline Restore and Protect, I think I will start doing a UOA after every 2 or...
Just arrived today. Despite having a printed shipping label, I was very lucky they found it. This UOA will be the 2nd Valvoline Restore and Protect oc.
The sample just arrived by good old wagon train.
Must have languished at the TV sitcom “Petticoat Junction”.
