He's referring to another thread in this section that got locked due to relentless spamming by another member here claiming that Amsoil will cure cancer, save the rainforests, and eliminate burnt toast.
OP- these trucks were designed with conventional in mind, run whatever you like (selecting a name brand is a good idea) and just ensure the level is correct at all times.

It has been proven that Synthetic will leak where dino does not.
Did the van not shut off in those 18 months? Hell, i don't know of over the road trucks that put 15,000 miles on a MONTH or 518 miles a DAY for a year and a half straight

i use regular oil.
i also will not use synthetic in a vehicle that was not designed for it.
my 02 went in for a trans fluid change. i specifically told them regular trans fluid. they put synthetic in it.
i refused to pay for the synthetic, because i told them not to use it.
3 days later i was back with trans low fluid .
and 3 days later again. and 3 days later again. after 4 times filling the trans up, they drained the synthetic out and replaced it with regular mercon.
that was 24,000 miles ago, and i have only put 3 quarts in it, all within the first 500 miles.

i run the mobil 1 5w 40 diesel oil in my trucks.it's good oil.i change every 9k miles using their extra large filters.
iv never experienced oil leaks due to the type of oil iv used.iv had plenty of oil leaks over the years in various cars/trucks but iv never blamed it on the dino oil lol.if you've got a oil leak,then replace the gasket/seal so it doesn't leak anymore with any type of lube is what id recommend.

advanced undercarriage protection system does not work when a customer comes into the shop complaining about an oil leak though.
first thing i always asked was "did you switch to synthetic oil?" was most often followed by yup.
and after switching back to regular dino oil the leaks went away.
