I know they have a "v-twin oil" but would it be bad for me to use M1 15w 50 automotive oil in my twin cam? Has anyone used it for a long period of time?

 

Skip has over 100,000 miles using the stuff. I have nearly 5000 on my current ride using it, and 30K on my old bike...I use it, and as often as I change the oil, I don't see the need to spend the extra $3 a quart for the V-twin stuff.

Skip will weigh in on this shortly.

Many use the M1 15/50 in their bikes and it works well. Fact is that most any oil if changed on a routine basis with the proper filter will give you a good long life from your engine. The key is to do it on a regular basis and you should be fine. The advantage to synthetics is better life at higher temps without breaking down as compared to dino oil, it will run a bit cooler in your engine and as far as I am concerned, I run the M1 V Twin because these bikes do run hot and I want all the protection I can get. Cheaper than replacing the engine even at $9 a quart.

 

After having the 15w-50 and the V-Twin versions analyzed, the biggest difference is in the ampount of certain anti-wear additives. The amounts of these additives in the car version are significantly higher than most other oils, and they actually matter only if you have a problem and lose the oil film between moving parts. In that case the V-Twin version might give you a little more protection. You have to be the one to decide whether the extra $4 - $5 a quart is worth it.

 

Interesting that this post came up so recently.

Was in Wally World today to get some brake fluid. Noticed that the had a pretty decent price for the 15W-50 Mobile 1, so I figured I would pick some up. As I'm cruising through the rest of the cool stuff in the auto parts...I see the Mobile 1 for motorcycles at $6.88 a quart, only $1.50 more than the car stuff. It was $9.99 at Checker Auto Parts, I double checked the price on the way home.

I won't pay $4.50 more for the motorcycle stuff, but I will pay $1.50 more...so I'll be running the motorcycle stuff for the next 5K miles.

Mac,

Our wallyworld has the same deal on Mobil 1 V-twin at $6.88. They carry both 20W-50 and 10W40. At my last oil change, I used Mobil 1 V-twin and I'd swear it run smoother than with the Amsoil, but that is probably just my imagination. I did order some Redline Shockproof Heavy yesterday and am going to give that a shot in the transmission. We'll see.

I swear that myself and I am not an easy sell, also a bit cooler on the temps. too.

You'll see a difference with the shock proof also, there will be little "fuzz" on the magnet on your next change.

 

I can't seem to find the M1 V-Twin oil. I've checked two wal-marts around here. where else have you seen it?

 

You can order it here and have it shipped to your door if you can't find it locally.

My local Wal-Mart doesn't carry it either but I get mine at Auto Zone.

Have a Great Day!
