Growing up on the farm we used Delo 15w40. Lately, dad uses Mobil Delvac. What was the first HDEO you folks used?
Do’h! I entirely forgot bout thatHey @53' Stude I think this has been discussed here before...
The first HDEO engine oil you bought?
I recall the first HDEO I ever bought was Rotella 15w40 conventional or whatever. Dad said his first was DELO SAE 40bobistheoilguy.com
For me personally it was Mobil Delvac ESP 5w40 in my Cummins Ram. Now I'm running Mobil Delvac 1300 15w40 and the next change will be Mystik JT8 15w40.
Just my $0.02
Interesting, I never knew they had an additive. I was only 6 in 2002 though so it was probably before my time.I started with Rotella 15w-40 back around 2002. Rotella used to have a diesel fuel additive back then that was very good.
I then moved to Delvac 1 that I would go bring back from Canada when I made trips up there.
These days it’s a mix of Delvac, Delo, Rotella and Schaefer’s.
Is it not? lolBack in my highschool days(early 2000's) I used to think Rotella T 15w40 was God's gift to diesel engines.
