if you run more than 750 hr a year on your engine's,low ash has benefits, if not, don't worry about it. low ash oil was developed for extended drain intervals, over the road trucks particularly, because of the reduction in piston deposits and the oils ability to suspend more particulates between oil changes. as far as brand, case does not make their oil, shell, mobil, chevron etc. makes oil for everyone, catepillar's oil is made by mobil, to their spec of course, but it is no better than mobil oil 1300. you need to look at the classification of the oil, that will tell you if it meets the latest spec from api, i.e cg-4, ch-4, ci-4plus, etc. we run 15/40 in everything from gas v8 pickup engines to JD and Cat heavy off road engines, no engine problems at all, seriously. i would run 15/40 in everything unless very cold weather, then use same brand/rating in a 10/30 for winter, most of the better oils/makers will offer their oils in both 15/40 and 10/30 for use in different climates/temps. find a brand you are comfortable with, whether dealer oil or oil company oil, and stick with it. oil company branded oil will almost always be cheaper and be the same as the dealer oil in quality if not better. consider availablity, and if oil scans are available as well.
