I've got 4 cyl car with almost 200K on it and it runs great. Used Mobile 1 from day 1, change it every 10-12K. Still slippery, but it gets dirty like dino oil. Change it every 5K on the HD.
Can't tell the difference as far as sound is concerned. I just trust the stuff. Too slippery in the clutch area though.

 

I called Exxon Mobil and they said they weren't at all impressed with you either............j/k

 

Guess I touched a nerve with some synthetic guru's.

 

 

Naw...just kidding...but if you want some good dino oil try Brad Penn Racing 20w50. There is a post about it here in the oil forum and you should be able to get it for less than the HD360.

 

i know there are die hard core dino users and hard core syn users i have used

both in 2 different bikes and the amsoil worked best for me the tranny shifts smoother

and no more metal schavings in the magnetic plugs use what you like and ride safe

 

Never seen it for sale anywhere?????

 

I googled the website and sent an email to their customer service on line contact form. They responded in about an hour and they have a distributor here locally. Not sure if they have one where you are but it is worth looking at. There are some guys selling cases on ebay for $55 & shipping but I would check with the company first. You may have a source locally. Here is the link:

Thanks for the link, I did read that it is pennsylvania oil with parriffin in it. The days of old there was a problem with this wax building up inside the engine, seen this first hand when i was working on cars back in the early 80's. maybe times have changed with this wax.
