I just switched to full synthetic at about 5,000 miles. Who else has switched over? I also still am using mobil 1 car oil.

woot woot.

Mobil1 Synth in all but my dirt bikes...

dirt bikes get oil change just about every ride so I get the cheep stuff in the proper weight depending on temp

Mobil 1 Synth is my oil of choice, but I bought some Castrol R4 for when I next change the oil. :)

using mobil 1 MX4T in the R6 and doing the R1 sometime this week or next week with the same thing.

Castrol R4 in it now. Switching to Redline on the next change.

nice!! how many miles should full synthetic last??

I go 3000 miles between changes, maybe less if I do some track days.

I guess I am Old School.... I plan on staying with Silkolene dino until ~10,000 miles before I switch over to full synthetic....:cheers

Castrol R4 Superbike:thumbup
