178k on 5.9 magnum V8. Been running 10w30 standard Mobil-1 (silver cap) every 3-4k intervals since bought in 2001 with 66k on ticker. Since 150k, I started rotating the M1 HM every-other OCI.
Jeep was retired as daily driver in Aug of '08. Since that time it has been driven only 600 miles. The vehicle has oil leaks, but not enough to leave spots on the garage floor, just enough to wet parts of the oil pan. I suspect rear main, oil pan gasket, & for sure valve cover gasket leaks but not 100% sure what all is leaking since it is not severe enough for me to have to fix at this time.
I had no noticeable gains of any kind between the M1 HM & the Silver Cap stuff although people say it is a very robust oil.
The Jeep will be used for light towing, camping, occasional mud bogging, going to the lake, snow/ice days. Some of this will involve HWY trips, some of it will be short trips.
I had planned to start using the M1 HM changed once per year or 3k miles (whichever came 1st). But in much reading and thinking, I decided to maybe try a dino or blend oil instead.
So I posted a lot of other threads, did online research, etc. and finally have it narrowed down to Maxlife 10w30 as the "other" oil I would be willing to try as an alternative the Mobil-1 HM formula I have been using before the vehicle was retired.
My questions are:
1.) If I do switch to the Maxlife permanently, should I then change the oil every 6 months instead of once per year since it is a blend and not full-syn?
2.) If this were your vehicle with the same pre-existing conditions and intended useage, would you want to change to a dino or blend oil or stick to a synthetic that will never see an extended OCI?
4.) Which base oil is thicker when comparing these two oils in 10w30?
3.) Will I hurt anything other than piece of mind by making this switch?
Thanks for reading an answering my questions!
