Engine oil OEM Toyota or PENNZOIL

Ultra premium is the best oil after amsoil, but amsoil is too expensive for this car, pennzoil is the best and cheap

I've been using penzoil platinum

I’ve used nothing but Pennzoil Platinum since the free oil changes ran out, 150k or so now, and never had a problem.

I prefer ultra platinum over mobil 1 since ultra is used with a group 3+ base oil, which has better heat handling than regular group 3 oil.

I use pennzoil ultra platinum 0w-20 and a purolator BOSS filter

I use Pennzoil Ultra Platinum 5w-30.

I change mine every 5k irregardless of whatever Toyota says. Oil changes are cheap insurance to your engine if you intend to keep it for the long term.

Toyota OEM oil has 10x the amount of thr dry lubrication additive molybdenum in its additive package. The dealerships use bulk Mobil 1 oil when they do your oil change. This is why everyone should change their own oil.

2020 Telluride with 80,000 mi still going strong with Pennzoil Platinum Ultra at regular change intervals.

I tried pennzoil and didn't like it. The engine developed a soft tick after about 3k miles. Went back to Castrol and the tick hasn't returned.
