Synthetic ATF Or MTL

I need a second (or third) opinion about primary fluid. I normally run Red Line ATF in my primary's but, the only place in town that sells Red Line products doesn't sell ATF (automatic transmission fluid, I know you knew that, just tryin to be thorough). The stuff the mechanic in the back recommended Red Line MTL. Manual transmission - manual transaxle lubricant. SAE 70W 80 API GL-4 Gear oil is what the bottle says.This is the only red line product for primary's they carry for red line. Is this for real? I'm just smellin a rat when the bottle says GEAR OIL 70-80 for my primary. Thanks

Got Valvoline Dextron/Mercron transmisson fluid that I got from Walley World in my primary.:rant:

Valvoline ATF...

I use the HD Trans/Primary fluid....

When I was young and used to Drag Race all the time, Valvoline is the only oil I would use back in the 60's

I guess I am the same as you in the aspect that I like to HD stuff when it comes to fluids. Not that I think that they are better, but it is just what is recommended so that is what I use. Not only that, I get a nice discount on everything from harley except for labor when I go, so what I end up paying is not that much more expensive anyways.

I think that Valvoline is some good stuff. I use it in my truck and for the wife's van. Never have any issues. Mobile 1 is probably the best though.

Nope.... no stinkin rat The MTL is the same fluid they sell in another bottle with V-Twin Primary Fluid label on it. Same thing with BelRay Gear Saver 80wt and their Primary fluid. Same stuff, just a different label.
I've been thinking about switching to MTL from ATF in mine
Red Line Synthetic Oil - Motorcycles, ATVs, and Powersports - V-Twin Primary Case Oil

Amsoil motorcycle 10/40 in my primary.

Don't the book call for 20-50 in the engine ?

I'm starting to change my mind about all this oil stuff.

Don't have to have the absolute best on the market.
I do change my oil often and keep it clean.

I ran my bikes for years with just dino oil

I want to walk in the store and pick the bottle up off the shelf.
Ain't gonna order something everytime I need it.

Don't remember any HD dealers here carrying Redline.
And I go in several of them all the time.:cussing:

I am a amsoil dealer, don't know how much is left on a 11 yrs contract I bought at 25.00 a year.
But I have to order it and pay shippin and put it on a credit card.
Got a Indy shop 30 miles up the road that carries Amsoil.

I like the Syn 3 oil from the dealer.

Also like the Castrol 20-50 V-Twin Harley oil Walley World started carrying.
And I like Castrol Oil too.

And don't sweat it, I'm not starting a oil war. I hope anyway.

Just making a statement that you can run other oils if you can't git what you think is the best.
