TRS Drive Oil
 

Going to replace the oil in my drives. I am using Valvoline Syn Racing oil in the engines & thought about using their High Perf 80w-90 or SynPower 75w-90 gear oil in the drives. Thoughts on either of these two or other suggestions?

Also how much is needed for a pair?

Ive always used mobil 1 75-90, royal purple 75-90, or amsoil 75-90. You'll need 8 quarts to do both drives.

Isn't the Mercury blue lube what you want to use?

Wannabe

i dont know, ive never used merc stuff.

use anything but royal purple merc has tested thaqt stuff and is bad ist hand knowlege here todd

Yup
 

USE THE BLUE. It's freaking high dollar, but it works. Bout $11 per quart at the store, u need 4 quarts. Essentially, it's like 75-80 wt gear oil, but don't use synthetic.

You talkin about the Merc High Performance (blue) Gear Lube?That's cheap! It's $16 a quart around St.Louis area!!

I just changed over to the Merc Hi-perf gear oil (blue in color) in my TRS drive. It took about 3qts and then I had to buy a 4th quart to top of the drive and fill the over flow tank.

The guy at the Merc dealer told me that when the oil prices went up to over $100 dollars a barrel Merc raised it.Then when it went back down they didn't!!:bsflag:

You would believe what merc says about another drive oil, when they are trying to sell thier own??

LOL,,i think your all color blind . The merc high performance oil is green !!!!!!!!!!!!!!!!!!!

And yes ,,its a little more dollar but hey ,,i use it and i think if they use it in they're drives then i should too. ?!:party-smiley-004:

:bsflag:I worked as a graphic artist for 27 years and I know I'm not color blind and I surely know the difference between green and blue! The high performance gear lube is blue!! Either way that's the good stuff!!

Is the Sierra HP Gear lube the same thing as Merc? A place here in town has it for $10.63 Qt.

I thought i heard one time that Sierra is just rebranded Merc stuff, as Merc is only sold at dealers. Not sure if this is true or not. If not i will keep looking.

I would be interested in knowing if the Sierra is the same formula, if anyone would know.

Or am i thinking of Quicksilver?

Quicksilver is Mercury oil. Its under a different name so they can sell it to other suppliers that are not merc dealers. They can only sell Mercury oils to mercury dealers by contract. So they just market it under Quicksilver.

ok thanks. this place had Sierra HP oil & for minute i got confused on the branding. I guess i will keep looking.
