Hi
I have  bought 10-40W fully synthetic instead of 10-50W. Can I still use in a 2020 interceptor

Liqui Moly 4T Fully Synth Street/Race 10W40 4L LQM20754

Moly & graphite friction modifiers are generally a bad idea for wet plate clutches. The molybdenum or graphite coats the clutch plates, maybe even creating unwanted slippage.

Multigrades are great. A 10W40 weight is fine in cool weather. The lower multigrade number is the equivalent straight weight thickness at the low temp standard test point. The higher number is the equivalent straight weight thinness at the high temp standard test point. Unless you ride in cold weather, a 15W50 or 20W50 works fine year round. Castrol makes a 5W50, ideal for air cooled engines subject to actual cold weather starting (20-30F).

Liqui Moly is a brand, not an indicator that there's Molybdenum in the oil, any more that you'd expect Castrol products to contain actual castor oil.

@ Cubix, go for it.

Yep.

Hmmm...so how do you explain all these writing implements I've been extracting from inside my Pennzoil cans over the years?
