Modern Buddy

Hi,

I'm planning on changing both the engine oil and gear oil on my 2009 Buddy 150. The manual calls for a SAE 140 weight gear oil but my local Pepboys only sell ones with a range on it (ex. 85W-140).

What's the collective wisdom's recommendation on it, try harder to find a 140-only gear oil or go with something that includes 140 in its range?

Much thanks in advance!

The owner's manual says 140, but the Service Manual (pg. 11) says 85W-140. I think you'll be fine.

most of everything that is sold will be 75w-140 or 85w-140 and straight weight 140 wt gear oil would be like frozen molasses on cold mornings; I use Amsoil Severe Gear 75w-140 synthetic without any quams; it is leftover from when I purchased my Rattler before trading it on my Buddy; this is also the stuff my dealer uses when they service Genuine scooters;

my hints to you are to run the scoot to warm the fluid so it runs out better, spin the rear wheel while on the centerstand to promote more fluid to come out, and consider doing another change in a few hundred miles and 'flush' the gearbox out in case anymore metal shavings remain after the initial oil change

What they said. Im using BelRay 75w140 now, and I bought somr IPone 80/140 gear oil from Scooterworks.com cause they have a great sale on it now. Its probably overkill, but I change it around the time I change the engine oil(every 2000 or so) because its so easy. Most people say 4000 intervals after break-in. I just saw some Motul 75w140 full-synth for about $30 or so a liter! Now that I would call a bit overkill.

Great tip about turning the rear wheel while draining!

Regarding warming up prior to draining: Warming up the motor will warm up the engine oil but to warm up the gear oil, you need to ride it a little. Oh darn!

Thanks much, guys!

when I said 'run the scoot' I meant ride it...I don't like to idle the engine just to warm up the oil...

Yes, I always try to drain them warm a well. And a others have said. The multi weight i fine ( better actually IMO).

The buddys don't shed much metal at all in the rear.. The stellas do though. I do a flush on mine when I changed the oil the first time.
