Engine oil Castrol or MOTUL

Prefer 10w40 full synthetic only.

i recommend u buy castrol fully synthetic gtx. Normal price 160-170 but during offer can get as low as 110-130 with free microfiber towel from castrol. Make sure it is shopee mall castrol. I have already bought 3-4 bottles and used it with no issue.

That's a good oil. I used it before I switched to 10w-50 Castrol.

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

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.

Im using Motul at Petron lang Palagi sa engine oil ko overall 29k odo na motor ko walang masamang nangyare ( ingat sa fake motul )

A3/B4 is a rating for just protecting the engine.

Castrol edge 5w-30 LL is oil with just C3. So it's mostly for protecting DPF. If you have a diesel engine with DPF then this is a good choice. If not something else would be better.

I used motul 7100 10W50 but couldn’t rate it as my bike simply was in storage for months after and it was a overkill as well, now using motul 5100 15W50, the heat control, gear shifting is awesome, let’s see what the mileage comes out to be

Currently using Castrol Edge 5w-40 fully synthetic, previously was using Estremo Heatpro 5w-40 FS, differences is so minimal to the point where you just neglect and forget about it....

Smoothness the same, silky smooth.

Car feels slightly like just slightly lighter on pickup with Castrol.

Started running Rotella T6. Happy with that...when my mechanic did a 12K service he used Motul 7100. It shifted poorly after that and I started to get a lot of clutch slip.
