i am trying to complile a list of reasons as to why my boss should stop using 15w-40 rotella diesel oil in our entire fleet.
we have 6 medium duty IH dump trucks, several cat backhoes, and about 80 gas pickups; mostly 2010+ ford f250s, with a few dodges, and chevys mixed in. we also have a few "passenger type" vehicles; ford escapes, ford station wagons, jeep libertys/grand cherokees, etc. we also have two ford hybrid cars (i forget what model). all vehicles are gas, except the dump trucks/equipment. 99% of them call for 5w-20.
using 15-40 in them cant possibly doing them any good, can it? these new engines are not the same engines made in the 80s. we have several pretty new trucks that have serious bottom end knocks/valve train noise. my boss thinks this is totally normal.
i was dumbfounded when i first started working at this job, and was pouring 15-40 into dodge neons. our fleet is plaged with oil leaks, low-hour engine failures, low-hour major component rebuilds, and general un-reliability. *i* think alot this stems from their "one oil fits all" approach. we only use one engine oil (15-40), one atf (atfII), and one gear oil (80/90). nothing in the fleet calls for atfII, or 80/90. yet we spend $28/gallon for some gimmick synthetic hydraulic oil.
am i over thinking this, or am i on the right track?
