Because that would make to much sense.If the oil doesn't get changed very often, then why not run an extended drain oil like HPL that can handle 20,000 miles?
Save money on oil changes and your engines don't get sludged up.
The one on my ‘11 Express 6.0 lasts around 7500 in mixed city/highway driving, guessing the OP‘s light had been on a while! Not sure if Isuzu requires Dexos or not, but my Express really seems to like RGT 5W30-doesn’t burn much & seems to be doing some cleaning from what I’m catching in my UPF48Rs.Just out of curiosity, when does the OLM reach 0% on this truck?
If the engine outlasts the vehicles ownership why spend the money on servicing it.For the amount of abuse, that filter looks good.
Personally, make whoever gets that truck to take into an quick lube every 3-5K. Dangle an extra hour of pay in front of them.
Nah-I'll keep doing them & shop for a new body when they get totaled! As long as my uninsured motorist property damage pays off! Back to the nasty 'Nati demolition derby!I'm gonna stop doing oil changes on my vehicles - they'll probably get totalled before the oil turns to sludge.
Been posting for years the oil filter [choice] is of relative insignificance . All that really matters is the filter not fail.A lot of this points to over worrying about oil filters. Flame suit on.
The 6.0 liter has a 6 quart capacity with a new filter. It was not upgraded like the 5.3 and 6.2.Does this 6.0 have an 8 quart capacity like my 2017 5.3? If so that may be what helps keep it running when neglected.
It's too much for one guy. I'm in charge of 60+ units from atv's to giant excavators. It's all I can do to just keep things running. Stuff is constantly breaking faster than I can fix them. Oil changes are last when they are screaming for me to fix a blown Hydraulic hose and replace 50 gallons of fluid.Don't you have a maintenance mechanic that checks all these trucks??? If not maybe you should.
