Owner reviews for engine oil

I’ve been using castrol edge euro 0w-40 for years and loved it. Seems to be discontinued, can’t find it anymore. That sucks, moving to mobil 1 euro 0w-40.

I run Castrol Power 1 in my KTM 350 4T. I'm just past 800 hrs with \~25hr oil changes. It meets the JASO specs my bike requires. I have not changed a clutch ever since I bought it at 280 hrs. I had the motor apart at 500hrs and the Nicasil bore coating was \*perfect\*. That was the last time I swapped out the piston.

I used to run 8100 Xclean EFE 5w30 for the last 5 years in my 2019 FA20Dit.

I use motul in my heavily modified car though because it’s just that good.

Make sure to use dexos GM approved oil or that thing will start making weird noises. I’ve only used Mobil 1 and not had any issues. Stay away from the cheapest stuff. You might regret it later.

If It's like the 107 1.0 it would be Total Quartz ineo 5w30. Total Quartz is the official oil provider for Peugeot engines and it's the one recommended by Peugeot although any similar oil should work.

I run Pennzoil almost exclusively. Especially, in my Dodge/Jeep because it meets the OE specifications.

I have religiously changed the oil every 5000 miles for the past 30,000 miles or so with Liqui Moly 5-W30. I think it consumes about 1 quart of oil every 1500 miles or so so I figured maybe this would help that.

I run the diesel Rotella T6 5w-40. My catalytic converter decided to start throwing P0420 codes around 58k miles and I spoke to a shop that I am going to have tune my car and one of the techs said that they reformulated T6 a few years ago and it has more zinc in it than it used to and that might have had an effect on my cat and it's early demise.
