Im using a 50 50 blend,.I use 15/40 semi synthetic and 0/30 full synthetic half of each.Where i live it does get down to -50 degrees and i should be running full 0/30 syn but the truck spends its life in a heated garage so really no need for full 0/30 in my opion.
Bjen i think all these trucks have crappy oil pressure via the stock oil gauge,i own 3 chevys 2 are diesels but both have crappy oil pressure.I just took a video of a cold star,its -2 f here right now -18 with the wind and you'll see that the oil pressure still isent that great.will post in a few min,gotta go get some Coke at the store,all this thinking is making me thirsty,.Oh i do other comedy videos also ill post one now for your viewing pleasure,its just me doing stupid skits im my garage for my kids,they love when dad is being crazy,.

Sorry dident see your last question Jben for changing the oil pump.Well im not to sure if you can just pull the bolts on the motor mounts and lift the motor up a bit to get at the oil pan bolts but i think its doable,crazy would no for sure,as for changing the oil pump its self thats the easy part,getting at its a different story,.I never really has a good look to see what kind of clearance there is under the truck to slide the oil pan out but i will check tonite when im in the shop

Ok finally got the oil pressure gauge installed and its not good news.I took the truck for a 20 mile drive to really warm up the oil and it was holding at about 23 to 25 lbs when driving on the hyw but once i stopped in my driveway and put it in park it slowly drops to about 5 or 6 lbs Now could it be a tired oil pump and the screen is starting to plug with sludge or would crank bearings do this also,im at a loss

Theres only 160,000 miles on it and pretty sure the last owner took real good care of it,regular oil changes ans stuff,uggggg dont no what to do with it any more.

Another question Crazy,i have a 1993 with a 6.2 in it that would fit but it has a mechanical pump,can i swap pumps to make it electronic and fit the turbo on.The 93 ran like a charm but the body sora fell off it,.My other truck is a 94 so think if every thing fits that would be my cheapest option.

with 160,000 i would pull the oil pan see if it ant clog up and maybe put new oil pump in and if you decide pull the pan run some oil cleaner throw it i just can't see it be the bearing if it been taking care of but who what can happen

on the 6.2 swap i be leave it can be done you have to use the injectors pump,turbo, intake ,exhaust manifolds timing cover,all the brackets and stuff of your truck

think you have to reroute the return line for turbo to back of 6.3 if i remember right and not sure about the Harmonic Balancer assy you have to do some checking on that but do know lots running 6.2 in there truck with 6.5 parts let know what you going to do if you decide i get list to getter for everything have to do swap

Ok buddy,,im still a little pissed of about this,well pissed at the guy i bought the truck from.This is the second time he screws me.2 yrs ago i bought a snow machine from him,it looked mint and ran well so i bought it.About 60 miles later it run like crap so i tear the motor down to find he changed a piston in it and put a aftermarket piston in it.Snow machines dont run well will a stock bombardier piston and a aftermarket piston,.They are both differant wiegs so i fryed the motor.I rebulit it then sold it,the guy who bought it 2 yrs ago is still running it .So now he sells me this truck and problem after problem,thing is we live in a small town and every one no`s every one,why couldent he tell me it was on its way out and save me buying it,painting it,changeing the front drive shaft cause it stripped the 3rd day i drove it,ugggg you get my point.Im not very pleased and am noted to have a bit of an irish french temper so i hope i dont see him any time soon but its a small town .. I think ill start drinking again and then make up my mind what to do,ha ha.Maybe ill just do a straight swap and dump the 6.2 in with out the turbo and sell the truck that way its sorta a easy swap other than a ton of cash for new exhaust and minor other stuff,,ok going to beat on the punching bag for a bit,..ill get back to ya bud

What about running that Lucas Oil additive in it, it states it will increase oil pressure but i know its thicker..... so to pull the pan you basically have to pull the motor, if I do that from reading above, check the screen filter and if its not clogged then maybe the oil pump.
