Picked up some Mobil 1 Racing 4T : V-Twin Forum: Harley Davidson Forums

vindex1963 · 09-01-2009, 08:41 PM

I'm going to try the Mobil 1 racing 4T 10w-40 in the primary this oil change. I have 4 qts of M1 15-50 for the engine, a bottle of M1 75w140 for the transmission.

I liked the ATF in my Softail Standard but thought I would try the Racing 4T just for the heck of it. Designed for the high H/P import bikes wet clutch, engine, and transmission so it should be good for a Harley's primary.

I go by the owners manual service intervals. 5000 engine, 10,000 primary, 20,000 transmission.

Let me know how you like it. I was thinking of going with either the Bel-Ray Gear Saver 80W or the Mobil 1 10W40 racing 4T in the primary.

I'm doing the service this weekend so after that I'll let you know.

Did my 15,000 mile service. Mobil 1 racing 4T 10w-40 makes finding neutral real easy. I started it in first while clutched and it didn't want to move forward like it did before. So far I like the Mobil 1 4T. I went with M1 75w140 hoping to reduce the "clunk" and it did help some. Kind of muffled it. I think with the extreme temps we get here that it is a good choice for the transmission and of course M1 15w-50 for the motor.

The bike had dealer serviced fluids in it so probably Screamin Eagle and Formula +. I bought it used with 10,000 miles.

I installed a fairing mount temp gauge and it didn't go over 230-240 in 90* weather. Highway at 75mph and stop and go traffic. 110+ temps will be another story.

I spoke to soon. Riding two up for 200 miles it ran 280-290 and went as high as 300+. I knew it was running hot but that's crazy. Sounds like I'm not alone either. The 09s are bad for this or maybe the 96" motor is. Cooler time. I started a thread in the 96" tech section.

If they've got them available now for the 09 Touring bikes, you should check in to getting a set of Xieds. They sure cured the heat issue on my 96".

I think it proves that one should spend some of that money saved on oil, on a set of cams............. maybe some headwork......

it is my understanding that the high heat issues with 07 and newer engines is all attributed to the new emissions requirements and the lack of catalytic converters. Heads and cams are great but unless the fuel is addressed these engines will run hot. Fuel systems to correct these high heat issues are readily available off the shelf.

They don't have them yet.

I really don't want to open up a brand new motor.
I picked up on your VERY little jab, we don't agree.
Accept it and move on.

That's an option I'm considering. I live in a place where 110+
isn't uncommon so I know the bike has to deal with a lot of heat.

It is not a jab, very small or not. The FACT of the matter is the EPA restricts the emissions of the twin cam. The only way to REALLY fix the problem is to change cams and add a fuel management system and have it tuned. Don't take my opinion, READ the forum and the opinions of the top tuners..............

V&H fuel pak ordered. Sounds like I need to address the lean before anything. I have a thread in the 96" tech going.
