I am looking for a replacement for Delo 5w40. I've been using it for over 15 years in ATVs, motorcycles, and other small engines (lawnmowers, snowblowers, generators, etc). Unfortunately, it has proven to be impossible to find locally right now, and I am essentially out. I cannot run a 15w as I will see temps of -30°F or colder during winter, and the ATVs generators, and snowblowers will all be used at those temps. The oil must be wet clutch compatible (motorcycles and ATVs both have wet clutches), suitable for a combined sump (motorcycle) and flat tappet cams. Ideally, it would also be a HDEO that would be suitable in ISB, 7.3 and 6.0 PS engines. I have not been impressed with Rotella in a HEUI injection systems. The bikes also didn't shift as well on Rotella as they do on the Delo.
Yes, I could stock different oils for each application. However, when I am maintaining over 50 pieces of equipment, having a "one size fits most" oil that I can change once a year is nice. Price is a concern as well, but not the end-all, I'd rather pay under $40 a gallon if possible, $65 a gallon is out of the question.
I've looked at the JASO list for 0w and 5w MA and MA1, nothing has really jumped out at me as being readily available locally. However, neither the Delo or Rotella are MA listed, despite the fact that both are well documented as performing well in these applications.
