Which oil?

I've just done an oil & filter change today on my old `83 gsx250 - a twin
air cooled jobie. At the Susuki shop the fella suggested 20w50 oil
which I greabbed, but now I'm worried cause the bike has labled 10w40 on
it. Will the 20w50 oil not be the best thing for it? Should I change it
back to 10w40?

Cheers

 

If you're in a really really cold place then a 10W might be necessary;
otherwise a 20W-50 is gonna' be better.

 

As above.20w50 will most likely do a bike of that age.My old CXs are
supposed to run on 10w40 mineral but it's hard to find so I use
cheap,"Duckhams Green" 15w40 with no problems.

It's always better to change oil more often than the manual says so
use cheap stuff and often.

Ooooooh!Contraversial or boring,you pick.

 

you left the 'r' out.................

 

10W-40 is only a guide. If you actually had the manual in front of you you'd
find that it's acceptable to use numerous different grades, and 20W-50 is
fine. Usually they only write 10W-40 etc on the cap though.
