Really no good reason to use synthetic if you change your oil that frequently. Very old school thinking from when everyone used single weight oils.
I was on the fence about using synthetic but with such a low mile truck that I plan to have for a good while I wanted to use some of the best oil I could. I ran synthetic blend in my last suburban up to 248,000 and it still ran strong when I traded it. I am considering doing the same but I changed it three times a year with 3,000 mile increments at the rate I drive. I was hoping for two times on full synthetic.

I run 13k-15k miles OCIs on my Burb with Mobil 1 15K mile oil... Blackstone says I could go further if I wanted to but my oil system isn't stock either.
Wow! That’s pretty impressive :eek:
