The Sup T has a parallel twin engine and everybody knows it.
It is okay to use either Amsoil for V Twins or Mobil 1 for V Twins in a bike that doesn't have a VTwin engine?
Is the Amsoil metric a better choice? I used to run 10W40 but I've been using Mobil 1 20W50 synthetic for a while now.
Sorry if it sounds like an oil thread!

The V-Twin labeled oils are aimed at the older dry clutch bikes. Get the Metric, which is intended for wet clutch bikes, like ours. Likely won't cause any harm short term, if you're in a pinch.

Amsoil 10/40 Metric. After breaking it in with Rotella mineral I've ran Metric in mine for 80,000 + miles. Amsoil's detergent package is top grade. 8)

No where on his list is Amsoil ,I wish he would of checked it out but I know its top notch... as far using auto oils in motorcycles try pulling in that clutch ,hitting the starter after it has been sitting a while . Hold on !! this is with the engine and trans together. (wet clutch)

I ran nothing but Amsoil Metric 10W40 in my Sup T until that damn rattling noise on cold startups. Went to mineral Yamaha 20W50 and it seemed to tame the cam chain quite a bit.
Then I switched to Mobil1 VTwin 20W50 and didn't particularly like it. Had it in the crankcase for about 800 miles. This evening I went out for about 20 miles on the freeway, hit 118 mph on the speedometer, not actual speed, and when I got home I did an oil change. I went back to Amsoil Metric 10W40.

How many miles do you guys think break in takes with dino oil before I should switch over to Amsoil? I am at 7K now. Thanks.

So with 7K roughly its probably broke in enough to change over. thanks.

Using Amsoil do you guys still chamge it out every 4K like Yamaha recommends?

Yippeee - An oil thread!!! We haven't had one around here in a surprisingly long time.
:D


Seriously, just stay to the recommended standard of JASO - MA on the bottle, so brand won't matter, synthetic or dino.


(Just don't mix synthetic and dino in the crankcase, of course.)

I just started using Amsoil Metric. Bike is new to me but previous owner had used Yamalube and various full synthetics. I have used Amsoil in alot of other vehicles and have been happy with it.

Read it somewhere why there is specific V-Twin oils. Usually V-Twins are "air cooled" engines with one cylinder getting lots of cooling and the rear one getting less. As it runs hotter on the rear cylinder, thicker viscosity with higher viscosity index is required to maintain that consistency of viscosity between the cooler and hotter cylinders. The focus is with the hotter running cylinder so that is is better protected.

How it affects a standard water cooled engines? Water cooled engines runs relatively cooler than air cooled engines and does not require the viscosity to be thick for adequate protection. Thick means more viscous drag and drops the efficiency of the engine and that probably means poorer gas mileage and less responsive.

Hm What oil would a Guzzi use then? Those guys must really be scratching their heads.
