Engine oil PENNZOIL or AMSOIL

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.

Been running amsoil in my Vitpilen 701. Same engine and it's been great. I run the 15w-50 metric stuff though.

I’ve run amsoil in all my bikes and still do. Same with all my cars and trucks. Never had issues

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.

For me amsoil signature series 0w20 a lot better than ravenol ehs 0w20.

I'm regularly using amsoil ss on my Honda L15z1 engine almost 7 years.

0W-20 Amsoil Signature Series 100% synthetic oil changed every 5k miles. Wix 57173XP filter.

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

I use Amsoil. While not on the official VW list as an approved oil, it is never the less formulated to the VW spec.

On the Gen 2 Prius that have been several reports of Pennzoil Platinum full synthetic consuming oil much quicker, me included.
