Hi gang,
I have access to Fabick/Cat UOA kits at cost, so I thought I'd give one a try. This analysis was sent in with my 55,000 total miles, 5,000 mile interval change on my 2021 GMC 3500 L8T gas 6.6 L truck. The oil used is Valvoline Advanced Full Synthetic 5W30. This is a Dexos certified oil, as recommended by GM.
I took some time to read online about what each of these amounts mean in terms of wear, etc. After reviewing the numbers, I agree with the lab interpretation that all looks good at this time.
My question is regarding the Valvoline oil itself. Can anyone in the industry, or with knowledge of engine oil composition, let me know if the additive package Valvoline is using appears sufficient for my engine? Is this an oil I can continue to use with minimal wear on my engine? This is a truck I plan to keep as long as possible...I'm maintaining the rest of the truck at severe service intervals, and would like to drive it to 250k miles if I'm able.
I appreciate your help, thank you.
Jeff
