Hey folks. I have a 98 300 Honda 4x4 with a 355 bbk , jet kit, EPI clutch, Webb cam , kibblewhites valve springs and supertrapp exhaust. I usually run Honda oil but last time shell rottella. Yesterday I bought Mobil 1 racing 4T advanced synthetic oil that is Jaso approved. Have you guys ever tried this and will synthetic screw up my clutches even thogh it’s jaso approved. It was 60 bucks for 3 litres lol. I bought valvoline atv utv oil at Napa for back up. Have you used valvoline atv oil? I’ve never run synthetic before and I’ve owned the bike 20 years. I was just thinking about winter and it’s -23 Celsius here as I type.

You'll be fine with any JASO MA (wet clutches) oil. Synthetics are far superior to conventional motor oils though, so you have made a very good decision.

 

[shadetree]

agreed ^^^^, you will be fine as long as its approved for wet clutches .

The price reminds be of a trip over to Germany about 8 years ago and saw the cost of a liter of oil as well as fuel, yikes

Pretty pricey over there ?

Here’s the oil

I use that sh*t everything!

Seriously, Mobil 1 racing t4 is the oil I use on my machines. Never had a problem with operation of clutches from the use of this oil.

I had this problem, with Repsol 100% synthetic,
but in the end I understood the clutch needed a light freeplay ...
However, I currently also have stronger springs

Here’s the oil

High quality oil for sure. But at - 23C (-9F) I know I would be reaching for a 0wXX or 5wXX though. That 10w40 is going to be thick at cold startup at those temps. Look in your owners manual and it will agree.
