Reviving a dead thread instead of starting my own. Has anyone used the Motul 8100 Eco-Lite oil on a 1.5?

I was looking at this on Amazon but the "does not fit your Civic!" warning gave me pause... https://www.amazon.com/Motul-ECO-lite-Synthetic-Liters-108536/dp/B07KCSR467

Next question is if anyone wants to double check my math... 3.7 quarts equals just over 3.5 Liters, right? Asking since every Motul bottle I've seen in the past are in Liters, not quarts. Thx!

That is a totally acceptable oil for stock or lightly modified cars. And yes 3.5 liters with no oil cooler, 4 with one.

I bought a jug (5 quarts) of that oil from two step performance, going to load it up in the next week or 2. I heard Motul was great for these engines and i couldn't find any Pennzoil Ultra Platinum in 0w20 available

Appreciate it!

Whatever 0/20 Synthetic the Honda Dealership sticks in there.....free oil changes for life when I bought my ride...and free lifetime warranty.

0/20 weight full synthetic Mobil 1

Torco Oil 5w 30. E85 breaks down 0w-20 too quickly.

Can't argue with that.

I am running Mobil 1 Extended Performance 0W-20 along w OEM Honda A01 oil filter. Usually do oil change around 6500 mile interval. My 2018 Si has around 20k miles now and she’s running perfect on TSP2 w Flex Fuel.

Although i have seen some people say to run a higher viscosity oil because E85 breaks down the oil a lot quicker, but i am unsure of that. Will have to look into that.

I am also running Mobile1 EP 0W-20, but on a modified version of KTuner's Factory/21.5 basemap. I plan to run a UOA at my next OCI, but don't expect to see any issues.

Purol Full Synthetic 0W-20
