I have a small landscaping business and have much equipment with small gasoline engines ranging from 5 to 17 horsepower. The manuals for most of this equipment seem to recommend 10W-30, SG, SH, or SJ oil. I've begun using Mobil 1 Extended Performance 10W-30, but I am wondering if perhaps Mobil 1 MX4T 10W-40 might be a better choice. My reasoning:
1) MX4T has a higher flash point - 253 vs. 224 degrees Centigrade, which might be beneficial in small air-cooled engines
2) The Mobil1 web site implies the MX4T has a higher level of zinc and phosphorus anti-wear additives.
Interestingly, MX4T is only SG/SH rated....
