I've been using Castrol GTX 10W-30 in my Jeep for 6 years, changing at 3000 miles. I used to be uninformed, and used Fram filters, but for the past couple of years, it's been Purolator or Napa Gold. At 86K miles everything runs fine, no oil consumption at all.
I've seen a few posts saying Castrol is bad for varnish, hasn't got a good pour point, etc. So I'm wondering, exactly what do you guys think/know about it? I guess since it's worked so far, I might as well keep it up, unless there's some reason not too, huh?
The engine seems in perfect shape, lived in NC for 3 years, then in WA state.
Any input?
Thanks
