Engine oil PENNZOIL or AMSOIL
I use Amsoil 20w50 in all 3. You don’t need a different oil for the trans. Amsoil is not cheap but I’ve been using it on my 03 FatBoy since new and have had no problems.
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
Originally switched to Amsoil for the Noack rating but stayed because it's just good stuff. I now run Amsoil products for all fluids in all vehicles.
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 only use Pennzoil platinum ultra. Only the finest for my baby.
I use AMSOIL 5W-30 for both of our vehicles. Never had any issues on either vehicle using AMSOIL.
Penzoil full syn platinum on my 02 and she’s chillin. I’ve never had issues
If you have ever rebuilt an engine that used Pennzoil, you would never use it again. The top of the head will be covered in carbon.
