that isn't really extended intervals. the manual recommends 5k on the engine, 10k for the primary, and 20k for the transmission, at least for 2007 and newer.

to make it easy for me, i change the engine every 5k, and then all 3 at 10k..... less to remember that way, and the tranny only takes a qt so no big deal.

 

One quick correction of a reply here--Red Line Heavy Shockproof/V-Twin Transmission Oil is not a 75W250. It is a very unique oil that acts like a liquid grease and it qualifies as a 90W. But, it's pressure agent that's suspended in the fluid gives the protection of a 250 on the face of the gears. You get the lower drag of a traditional gear oil and the protection that a heavy gear oil would provide. That's why most Top Fuel and Funny Car teams run it in their differentials--they get extreme protection with relatively low drag. We make Shockproof in 80W and 70W weights, too, but they are not used in these V-Twin applications.

I think the forum member that is suspicious of our lack of criticism of other oils should go back and read my post. He's right, we don't make claims or bash other products. We let the oil's wear results in actual engines and our documented use of superior fully-synthetic raw materials stand on its own. Anywhere else, many of the products in the marketplace would be restricted from use of the label fully-synthetic.

The experts on forums like this that have actually seen their parts after using our products (showing lack of wear on their gears, bearings, pistons, bores, and valvetrain) are the people who can rightfully speak on which oil is better. That's what counts, lack of wear on the parts, better ring seal, etc. We don't publish testing to debunk other companies ad campaigns. We let the results of our product in the actual applications do it instead.

One last suggestion. Try a back to back temperature test trying a few different products. We think you'll find a signficant drop in trans, primary and engine temps compared to other products.

As for where to buy it, Racer Parts Wholesale, Summit, Jegs, and even our own site are solid resources. More than 100 Cycle Gear stores have it on the shelf and we also are now distributed through Tucker Rocky/Bikers Choice. Zippers does a good job for us, too. Many of our automotive distributors sell the motorcycle products, too.

Was the Severe Gear the heavy viscosity (~85w140)? If so I'm surprised you noticed much of a difference, as I changed from Royal Purple 85w140 to RLSPH and didn't notice any difference at all, which was good because both products really quietened and smoothed-out the tranny. I only changed because the RL gear oil is $4/qt. cheaper in this area.

 

As I said in an earlier post...I 've been using Redline for years and typically buy it from my indy. I went to the HD dealer the other day and noticed that he now stocks it!

 

Damn Doc, I got a chill just thinking about it!!

 

You misunderstood, or read my post wrong. I never said Amsoil or Mobil 1 was better than Redline. I said they were as good, IMO. I don't sell Amsoil! I'm using it right now because the Dealer that was servicing my bike sold it for the same price as Syn3. I have started doing my own service. I don't like the way Amsoil is sold...like Mary Kay or Amway products. I like to buy stuff off the shelf. That's why I'm switching to Mobil1, I can buy it at my local Advance Auto. I checked on Redline because I see alot of forum members use it,but no one sells it near my zip code. My selection is as good as any until it's proven on independent testing not to be.

Mobil1 20W50 V-twin Engine
Mobil1 ATF Primary
Mobil1 75W90 Tranny

Faast ed, Please note, I said (AS GOOD!)

 

Haven't changed the oil in a couple of my shovels for a long time. keep adding used engine oil from my truck and cars to them when it gets low in the tanks. Ones a 72 ones 1978 owned since new stopped changing the oil in them in the 80s, just dump used oil in those pigs as it leaks out. Ride them every summer and i know the gear oil has been in them for over 20 years. Wonder if these Amsoil and Redline oil users bikes will run and shift that much better down the road? Most buy the oil cause they like the picture or the color of the container.

 

gonna try it it my fxdwg the next round . Heard nothing but good about it . I am in Canada and had a hard time finding it ,but did find some . So lets just see if it lives up to all the hype.!!

 

Well, if this matters; Redline's been living up to the hype since 1977 for me in all my racing and street vehicles, including race karts and dirtbikes I've had whether ,2 stroke or 4 stroke.

PS - They also have a great synthetic suspension oil that doesn't foam like petroleum oils.

 

What's the difference between Red Line Heavy Shockproof and v-twin transmission oil with
shockproof all -synthetic . Is one better than the other?
