Engine oil PENNZOIL or Pentosin

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.

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

I often find Pennzoil Platinum Euro LX at 37$ for 5L at Canadian tire. They are all great oils.

Penziol platinum on my 23. change it every 5k and it’s still golden

Decided in the 5w-30 because the engine seems to run a bit smoother with the 30 weight

I use Pennzoil "Ultra" Platinum for my 2010 with 5.4 Triton and it runs amazing. At one point I did try Royal Purple but my engine was actually noticeably noisier so I switched back.

I used Valvoline synthetic in my first SHO, and I am using Mobile 1 in my latest SHO. I tried Pennzoil in my 5.0 (Windsor) and all the lifters started clattering.
