Snozzle. I had redline light weight in the 33 with unknown kms. Smashed in some castrol syntrans or syntrax (the pricey synthetic one) and it was fuxed. All gears felt like crap. Crunching, grinding all with NORMAL driving. So i dumped it ($100 worth of oil) and put in the light weight that i saved
All sweet except it now crunched going into 5th hmmmmm.
Fast forward 8 months or so of this and i had enough Put in new light weight and it's crunched once into 5th in 3months instead of every couple of days. I say no to castrol!!
