oil weight...

just seeing if it would be a bad thing to run 20/50 in my 1982 gpz 750...i did do a search, but nothing worth while came up.

i use 20w50 in all of my air cooled bikes in the heat of summer. i switch to 10-40 in the spring and in the fall

It would not be a bad thing but it will rob you of power. Even Ford motors recommends 5W-20 in their Mustangs to increase power and fuel economy. If you run the lightest Shell Rotella-T you can find in your bike, It will give ALL the protection your bike will require without breaking the bank and destroying your power and economy. I run 10W-30 in my bikes and I think that most guys on this web sight will agree. It would not hurt anything if you add a few OZ of the new "Rislone with ZDDP" to your oil either. I buy my Rotella at Walmart in 2.5 Gallon buckets for about $23 when its on sale.

ive used 20/50 synthetic for years without issue,due to the way its made it has the basic consistancy of 40w dino bones but lubricates much better

i run 10-30 in the winter,in my truck! :laugh:

Apparently you prefer to pay more for your oil which is OK if you have the big bucks. Us poor retired people have to save it where we can

I run the Rotella 10W-30 year round in the bike. Here in Chicago I ride down to 38F and it can get as hot as well over 100F.
