Low oil pressure

Thanks; I asked because my son and I have been looking at different synthetics for his new 340 after some miles are put on it. I passed this one up because the product guide mentions additives for moto clutches, but I'll look into it more for summer use. It IS rated SJ so that seems good.

One thing I have noticed in using Mobil 1 products for a loooong time is that they seem to consistently be thinner at cold temps than other oils of the same viscosity rating, and looking at the 'pour point' shows this; this product has a -42C pour point as opposed to a -24C pour point for Valvoline VR1 20W50 and -27C pour point for Brad Penn 20W50. Another full synthetic shows -45C pour point for 2 Redline 20W50 synthetics (ester based).

IMO, one thing that is helping you use 20W50 year round is your location in southern CA, near San Diego. So your good experience is for a warm climate and is likely not as applicable to cold climate use of 20W50. Redline recommends not using their 20W50 at low temps at around -5F and below.
