Owner reviews for engine oil

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

Based on my own tests, I found the AmsOil to be the best at reducing heat a few degrees. It's not cheap, but it's still cheap insurance, all things considered.

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 run 300v Motul. Much better than Motorex cross power in my bike. Also tried Motul 7100 but that was no better than the Motorex. Have to change oil at 5000km with 300v, but I do that anyway or earlier.

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

It works great, maybe a bit expensive. I've run used oil analysis and change it 3-4k miles based on aluminum wear. I don't see a reason to use something else.

I use Mobil1 ESP 0W-30 personally

I used this because it was on sale:

Liqui Moly - 0w-30 Oil (5 Liter) Top Tec 4210 (504.00/507.00 spec)

I figure if it meets spec, cheaper is better for a midcycle top change.

So I had this same question because I assumed that my local Toyota stealership would use “Toyota” brand oil, especially since they charged $70. Come to find out they used Valvoline.

I would run Castrol over Pennzoil. Coming from personal experience, Pennzoil is junk.
