A while back i asked for a "go to" oil and Rotella T5 10w-30 was highly recommended. For about the same price i have found Mystik JT8 in 10w30 and 10w40. I bought some of the Mystik to try for now.
This oil will be used in Gasoline engines (i don't own any diesels)
my concern is that one of the tractors i plan to use this in is very heavily sludged. it has a long history of neglect to be sure. the PO just added some oil "once and a while" without regard to oil level, when i got it it was 5qts low on oil - it's a 7 quart system.
since i've gotten it, i keep the oil full, and only change the oil when it starts to get enough fuel dilution in the oil that it starts to lose oil pressure (3 times in 7 years). most times i don't change the filter, just drain and add fresh oil. i've been using walmart supertech oil 10w30 and trop artic as of late because that's what's cheapest.
this last time i did change the filter and actually stuck my hand down into the filter canister (it is a cartridge type filter) and found no less than 2" of sludge at the bottom of the canister. I don't know where the filtering system is even functional to be quite honest. I imagine that the rest of the engine is equally as dirty inside.
so .... the question ... what do you suppose a HDEO would do when used in an engine that is known to be very dirty?
I don't care about cleaning it up. i have no interest in even trying - there's no point. The motor needs a complete rebuild and fouls out a set of plugs in less than 8 hrs of run time (and uses about 3 quarts of oil in that time frame as well).
my only interest is keeping it going long enough to save up the cash and time it takes to rebuild it - expect another 5 years before i can even think about rebuilding it. If the HDEO would clean the motor, that's fine so long as it does no harm.
just curious if the HDEO, with it's high detergent load and ability to suspend contaminates in the oil might actually do more harm than good. perhaps i should use a PCEO like i have in the past? maybe it makes no difference?
interested in your thoughts!
thanks in advance!
