10W60 motor oil
I have good prizes on BMW oils. They have a 10W60 oil for the M performance engines.
I see that BMW M engines in general run tighter bearing clerance than we typically do in our Pontiac engines. 0.00160 inch on mains and 0.00135 on the rods, on the S65 engine as an example. This oil is a low friction oil, to help with fuel consumption, that should help in adding horsepower too. What do you think about running an oil like this in a built street/strip Pontiac engine? |

I think you are looking at a solution in search of a problem. No way would I even consider using it.

That's gotta be some thick stuff! I don't think that would be a good match. Hard to believe it's used in tight clearance engines.

The most over talked about subject in Hot Rodding.
Usually does not amount to a hill of beans. Most important thing about is is picking one for your climate and changing it regularly. |

Keep the viscosity as close together as possible not as far apart as possible.

I'm not sure what BMW would use 10W60. Modern M cars use 0W40 or 5W30.

It is used in the V10 and V8 from E90 and E60 era. Maby it was developed for track use and high rpm applications.
GM recommends 20w50 or what? I feel 10w40 fully syntetic should be nice, but there are so many different views on this subject. Full roller ofcourse. |

Top fuel cars run a 70W oil because of the amount of fuel dilution that takes place during a 4 second pass and after pumping over 6 gallons of fuel thru the motor in that time frame.
I really can’t fathom the need for a 60W oil, but I am sure they will make one up so that you have to come to them for a oil change that cost $160 bucks, that is if they don’t have to take half the motor apart to get to the oil fill cap.

My son’s 2008 M3 BMW calls for the 10-60 oil. That engine (S65) has a factory redline of 8,600. Really sounds quite exotic to hear a v8 rev that high.
On a cold start you cannot rev over 4000 or so or a soft limiter engages. There is an oil temp to rpm ratio display on the tach. RPM can increase as oil temp rises.

Try it and let us know how it goes.

I will stick with my 15W40 oil as the car does not get fired up in below 50 degree weather.
And the BP Oil (Oil Technology Expert) recommended it for my flat tappet camshafts. Tom V.

Normal operating OIL temp is 210-215. Interestingly there is no physical coolant temp gauge.

Does not hurt to have high zinc oil but even that will not save a lifter that is ground flat. |

If you live in a colder area yet have low oil pressure due to a worn bottom end, it may work nicely. Wouldn't use it in a "good" engine though.

I had a Melling RAIV cam with Johnson lifters in my 455 for about 20 years. Had been running Rotella oil for at least 10 years. Used to run 20w50 before that. Then , one day it wiped out a cam lobe. I heard that they removed the zinc from Rotella. I never researched to see if that's true or partially true. That seems like pretty strong proof that it's not just parts. I agree that it's probably both parts and oil killing the flat cams these days.

I read that it was because they started putting catalytic converters on diesels? The zinc fouls the converter?
