If I remember correctly, Redline's MTL or Primary oil looks like normal oil, not the signature Pepto Bismol red. I never use any of Redline's Shockproof oils other than "Heavy", so Cromagnon could be correct that it may be Lightweight Shockproof, either way I would still change it as you probably don't know how old it is and you'll know exactly what you'll be putting in vs. guessing...

That's Redline Heavyweight Shockproof. I've tried it, and the Lightweight Shockproof, which is blue. Both were OK, clutch worked fine, but shifting was a little clunky with both. I've tried Mobil 1 75w90, which also works about the same as the Redlines.
I have been trying different stuff, just to see what seems the quietest. I now have Valvoline Durablend 80w90 gear oil running , and it's been the best overall for smooth clutch engagement and 'snap instead of clunk' shifts. Maybe the combo synthetic and dino is the best of both worlds. About half the price of full synthetics too.
Next motor oil change, I'm trying the Valvoline 4T 20w50 motorcycle synthetic that's now at Walmart for $7.99 quart.

Thats why I corrected myself in post #14
The Red Line Synthetic Primary oil is red or could be called a red tint, otherwise it looks and pours just like motor oil, dont know about MLT

Must have missed #14, sorry. MTL or Manual Transmission Lube is also made by Redline and is the same product as their Primary lube in a different package.
