The recommended grade oil is 0w-20, but many people also run 5w-30 with no issues ☺

Have been using this oil from new. It is the 'recommended' spec:

Mobil 1 5w30

Mobil 1 5w-30 here too, it’s very good oil.

Other brands are equally good too it’s just your preference.

I always used Motul stuff, seemed to do the trick 👍

Agree with Moyz - I have been using Motul 300V 0W-20 and it's fantastic stuff.

Have a look in your owner's manual. It gives you the recommended oil grades and a temp chart to go with.

I use the same oil as mentioned a few comments up, the petronas 0w20 from Suzukishop.

Another vote for Mobil here but for 0W20 as recommended by them for the 32S:

Only trouble is it only seems to be available in 1 litre bottles so is pricey and not always enough bottles for a full change on the shelf.

Does anyone here have experience with Red Line 0W20 oil?
