Thank You in advance
The only M1 5w40 I have used is Formula M … hard to find and priced more than 0w40 …
Are we talking Delvac 1 for the 5w40?
Seems D1 is mixed BO (some PAO) and M1 0w40 is GTL
Never heard of Formula M
All i see is M1 TDT 5W40. Rural King had M1 TDT for $20.99 so dad bought max he could for rebate

I actually like haviing ZDDP and Phosphorus in my oil as anti-wear additives.
I prefer to not use low-SAPS oils if I can help it.
Dad plans to use the TDT 5W40 in his 80's Dodge diesel P/U. Thanks
