Engine oil MOTUL or IDEMITSU

Have it in my N55 and it's very happy.

I recommend this. used it for my m550

holds up very well. the car likes it. the thinner OE spec oil kind of evaporated a bit after 4-5k miles but this one hasnt.

I have a block heater, and use high quality synthetic oil (Motul 8100 5W-30) .

This is normal. Wait till it gets below 1k rpm. Modern engines do not need a lot of time to idle after cold start, the ECU handles it. Although, for a few kilometres, do not push very hard. The engine oil (0w-20 idemitsu) is thin, and needs time to lubricate well.

For 2W Motul is best.

I don't think you will find anything but Selenia as "approved" but you will find plenty of "meeting specification". I know that meet the -GH2 spec and those are Motul (which I use), Fuchs and Ravenol. But long story short...match the specification designation from a good oil brand and you're golden

Always had good results with motul

We're big Motul guys around here!

So if you review the virgin oil analysis database, it includes idemitsu 0w-20 and 5w-30 and for both, the TBN is rather weak in comparison to other more readily available blends, also, the viscosity at 9.5 cSt for a 30w, some 20w come close to that. Does any of that matter? Not a whole lot, but it shows that there's nothing special about the oil. Generally speaking, higher TBN is better.

I was using Motul 7100 before 2nd service and after switching from Prolube. Service center guys insisted like hardcore, to go for prolube because of warranty blah blah. So i switched, and ive just ridden about 100 km now the bike feels like crap. Will switch back to Motul.
