oil viscosity

{"text":"I just had a no oil pressure warning light come up coming down the i70 in Colorado last week. it's a bankruptcy fix 😭. worn bearings, the whole nine yards. I'm not really getting good information from the repair shop, and waking up from my sleep, I don't know if my choice of oil had anything to do with this break down. I've run so many different scenarios and I almost feel that I'm at fault. I changed my oil every 4 months, I usually run 4k-4.5k miles a week, but I never did an oil analysis.\n\nI would think if the oil I used was too thin, that you would notice gradual changes in oil pressure or noise in performance. But I guess humans aren't great at detecting gradual changes in noise. Going down the hill with engine brakes on, the engine was still turning smooth, but loss oil pressure and engine shut off. after.that, the engine still turned on and turned over very smooth. So I don't believe it's the oil viscosity, but I want to poll around to see other's opinion.\n\nwhat type of oil do you run? and has anyone experienced a no oil pressure problem?\n\nI was running a 15w-30 full synthetic from triax.

255377 发表于 2019-12-17 19:34:29 Oil type doesn’t vary much between brands according to people that have tested performance. Oil service intervals are listed in the owners manual. You should stick to the service intervals religiously. You can tell that your engine is getting worn out by looking at oil consumption. This means that oil is bypassing the rings, due to wear, and is escaping out of the exhaust valves hence the oil loss. Checking your oil level regularly can help you from running low on oil and will let you know when it’s close to time to schedule an overhaul. Although at 25k price tag it may be wiser to just get another tractor being that they’re less than 50k for a solid used unit. As a general rule, 1 gallon every 3 thousand miles oil consumption is cause for concern and it’s at that point you’ll have about 1 year left give or take on your engine life.

","text":"my truck had almost no oil consumption, 7-8mpg before breakdown. 50k is a new used truck, but my truck was also a used truck.","replyToPid":284917}

{"replyTo":"","text":"possibly the oil pump drive broke or possibly the relief valve, if the pressure dropped suddenly. How many hours on the engine? That'll tell you more, if the truck runs all the time and sits and idles when you're parked the hours will be alot higher than someone who shuts off the engine over night etc. These engines are not designed to idle for long periods, that's why there's a high idle.","replyToPid":0}
