1990 Nissan Pickup
2.4l ka24e (SOHC)
130,000 miles
This truck runs great, and clean, uses no oil. Used to commute 4 miles a day plus maybe a little runaround time on lunch and weekends. Not putting on much mileage.
I am currently using M1 10w-30 SS with Napa Gold Filter. Temps here in the ATL have been 20's in the morning (some 30's and 40's) and 40-50 in the afternoon. But I digress....
The engine is a little noisy around 2,000 to 2,500 rpm's, especially when cold. I know that it's not the timing chain or guides, because I did a complete kit in November. Before that it was really loud for the first 3 seconds of running. I don't think that this noise is hurting the engine, but it annoys me a bit.
It may be valve tapping, or piston slapping (doubtful on a Nissan), or little gremlins under the hood, i don't know???
What do ya'll think would be the best oil to quiet this mess down? By the way, it does get much less as the engine warms up, but I don't usually get to peak temp on the way to work unless I warm it up in the driveway.
I've heard the "m1 makes engines louder because it's too thin" argument and the "you need a 0W oil to get good lubrication to the tappets on those cold mornings" argument. Both sides seem to think that either thinner or thicker is the best way to quiet an engine. It can't be both ways (can it)?
I'd like some input. This is my first Nissan and I don't know what makes them happy. Should I try GC 0w-30, or maybe a 15w-40, or even 20w-50 (not in winter)?
OK, discuss.
