GSXR 750 L8 (aka 2018)
Up to 1833 miles, since Feb 15, 2019 the day she was picked up from the dealer's warehouse, uncrated, prepped & delivered to lil 'ol moi.
Abysmal ride time I know but it has been raining a lot (!strangely coinciding with my days off grrrrfffuk!)
But back to foRUM topic...Ecstar r9000 full synthetic ordered and soon to be delivered w/new filter & crush-washer.
Still using Ecstar r5000 mineral oil thru the first 2,500 miles. Will do r5000 again @ 2,000 then change to full synthetic @ 2,500
When the warranty expires @ 12 months, prolly gonna go to Mobil 1 4T full-synthetic JASO MA2 but wanna finish warranty with 'zuki's recommended Ecstar ('zuki said they guarantee it lol).
I know some things about some things but I don't know jack about a whole lot more.
