Engine noise--Mobil 1 vs Redline

[brucelee]

I just went through a sequence of Mobil 1 to Redline to Mobil 1 in my Buell XB9S. Since this engine is air cooled and right out there, the noise level is fairly clear and distinct.

My verdict! The Mobil 1 15W-50 is clearly a quieter motor oil than the Redline 20W-50 that I used in between. At first, I wasn't sure if I was imagining the increase in noise. However, when I switched back to Mobil 1, the difference was very clear indeed.

Go figure! I estimate the RL is like 30% nosier in this particular engine.

Thoughts?

Yes, it might be all in your head, or at least 75% so...

had the complete opposite observation (that the red line is quieter) in Ford 4.6L SOHC engines.

 

[Steelers]

Agreed, M1 makes 4.6L Fords sound like clatter boxes. Mine runs quieter on GC or reqular old dino.

Just toss all that synthetic junk away, my son. Go back to Castrol mineral conventional oil, and syn no more.

My comments-

Not all in my head. I had actually expected RL to be quieter. It clearly is not in this motor.

I would not use DINO in any machine I actual intend to keep.

 

[brucelee]

Oh for you Ford guys, were you running Mobil 1 15W-50? Of course, you were not.

My comments are specific to the weight oils I mentioned. I make no assumption this noise issue is consistent across the Mobil 1 or Red Line oil lines.

brucelee; Did you ever track (drag strip time trial) that bad boy, and if so, what did it run stock and/or modded?? I know it's designed to be a great handling bike, not a sraight line only deal, but I was just curious, what with all that bottom end and light weight and all.

 

[brucelee]

No, I have never timed the bike in the qtr. I did add the Buell race kit which did add so go to it. The magazine says 11.7 in qtr but who knows?

It is a nice torqey bike and handles really really well. Certainly there are faster straight line bikes but in the twisties, it is a TON of fun.

Thanks
