Just bought this from an online auction.
1998 GMC K3500 4x4
5.7 w/ 110,000
I believe it has had low oci with 5w30 dino. I believe it calls for 5w30. I would really like to use some Rotella T5 10w30 that I have, but also have a jug of PP HM 5w30. I am in Illinois and see temps from -10 to 100+ and will probably do annual changes or 5k.
Which oil would you use and why? Thanks!
