I have heard on this site many many times how M1 oil has made their engine more "noisy" and what not, and if they switched to brand X oil the noise went away.
I have something that I just noticed. Here in Southern California we dont really experience "Cold" weather like other areas of the world or country to that part. Well, the last couple days we have had a cold front come into the SoCal Deserts and temps have been in the upper 20's in the early morning hours.
I have noticed that when I start my car up the engine is what I would consider "nosier" and was trying to figure out why that would be. I cant really believe that X brand 0w40 can be quieter than Y brand, so I was trying to figure out what the "noise" actually is.
My car is a DI, or Direct Injected motor, and I feel as the Temp drops, the High Pressure fuel pump that is pressurized by the cam shaft may be responsible. Its possible that certain mechanical parts may just be susceptible to more mechanical noise during cold weather, vs warm weather. Maybe folks feel that brand Y oil is quieter than brand X is due to the time of year that the oil was switched? Or do people actually have some type of proof that one oil can actually make an engine quieter. If your using the same weight oil and same specs. how can there really be that much of a difference?
If anyone has any other ideas or can shed some light on the fact, or is it that one oil can actually make your engine nosier?
