Engine oil Mobil or MOTUL

Personally I've mostly been using Mobil 1 15w50, as it's almost never run in the winter.

Mobile one full synthetic hands-down. I have a 2004 Toyota Corolla and a 2007 Toyota Tacoma I’ve owned both since brand new and now both have over 260,000 miles apiece . I have only used Mobil one full synthetic changed every 5000 miles. just took a bore scope to look into both engines a few months ago. They look like they’re brand new. Almost no varnish. Absolutely no sledge, never had any problems whatsoever with these vehicles. It’s insane.

my vehicles use only Mobil 1 oil.

Prefer 10w40 full synthetic only.

I have used Motul and Castrol before and I found the Mobil oil to perform and keep the engine cooler and smoother on my triumph.

this oil is used in a dominar 400 and has been used for roughly 1500km before the highway ride in heavy and light city traffic. my opinion of this oil so far is pros:-

it's very consistent so you know what to expect from it

maintains its smoothness even at higher rpms/ speeds

the engine remains cool on the highways but again this can be attributed to the excellent heat management liquid cooling system of Dominar 400

oil drains can be decently long 4-5k km if the motorcycle Is liquid-cooled( it will still have some life left but hey please change the oil at 5k km)

it's a clean oil, and it has detergents that will keep your engine from having sludge deposits

cons:-

as soon as the engine heats the gear shift experience is a mess, its okay to switch between gears but getting into neutral is hard

higher priced compared to other good brands like total hi perf, but lower than Castrol

also, this is a big one I've heard and read on other motorcycle forums, ester-based oils can be bad for gaskets and seals in the long run.

this oil is kinda bad to use in an air-cooled engine, because this oil evaporates and decreases in level, in an air-cooled engine this will be a mess as this oil from what I can understand and feel was designed to go into a liquid-cooled engine and this does a poor job at transferring and absorbing heat. seen many cases of oil level drop when used in an air/oil cooled motor

most importantly there are a lot of fakes of this oil in the market so to source the genuine one just go to a KTM showroom if your bike uses 10w50

verdict:- good oil for the price, looks fancy with the red colour, does its job well, and will last 5k km easily on a liquid-cooled engine

Mobil 5w-40 or Liquimoly. 10w-60 for hot summer track days.

Just make sure it’s SP 0w30 I personally run the euro spec castrol which is the same at the BMW bottle. The Motul SP is also good.

used mobil 5W-30 while ago, discovered it consume oil too fast. after that i’m stick with seasons cheapest LL01 approved oil. Elf 900FT 5W-40 for several years, going to try Penzoil 5W-40. N52 consume oil anyways.. but bit slower than 5W-30.

I was running it in a VR6 engine, and couldn't believe how much extra chain and lifter noise there was. I put up with it for a couple weeks, thinking it might get better but it didn't, so I switched to Castrol Edge 5w-40 and noticed the difference immediately. Noise means wear, so I feel comfortable staying away from M1 for my VR6 engines.
