Changed the oil on my 1985 Toyota 2WD truck yesterday after work, thought I had all my act together. Had 2 five quart jugs of Castrol 10W30, one with just 1.5 quarts left, the other full. So went ahead and drained out the old black oil, removed the filter, took the O ring off the new oil filter, dipped it in the old oil, reseated it on the new filter, slapped on the new filter, put the drain plug back on. Then poured the 1.5 qts from the partial jug into the engine and grabbed the other 5 qt jug. Opened it up and the oil was all black  I guess this was oil I drained from the last oil change over 8 months ago and never got around to recycling it. Well I needed 4 qts total, luckily I had a spare 1 qt bottle of 10W30 in the trucks tool box, so poured that in and now I need another 1.5 qts. I wasn't about to drive the truck that was that low on oil to go get some more, so I took my other truck, a '03 Tacoma, went to Target, snagged 5 quarts for good meaure, and slapped 1.5 of them in the engine of the '85 Check your fresh oil supply !  The Mobile 1 5W30 supply for the Tacoma was ok, 6 quarts on hand |

This was my 63rd or 64th oil change been doing them every 4,000 miles, now doing every 5,000. I think when I get the oil changed on the Tacoma I'll use the 5000 miles used Mobile 1 oil for the 1985 truck, if the 85's still running. The Mobile 1 is a light to dark orange, never black after 5000. Has 260,000 miles, had a new head gasket at 192,000, but now it's sucking coolant, no white smoke, no visible leaks, no oil in the coolant, no coolant in the oil, new radiator cap, dunno where the coolant's going. Time to consider a replacement for the old truck in 6-12 months |

So long as you didn't leave the filter loose and blow oil all over the place, its all good. An engine will run a surprisingly long time with little or no oil at all. Don't ask how I know this.  BTDT. Had a buddy come over while I was getting ready to change the oil in my old Explorer, and he decided to help. Well after we got done and I went to start it up, oil came pouring out all over the place. Soon as I saw it I knew what happened. I asked him if he tightened the filter all the way? He said he did. Apparently, he did not. 
Big ass mess all over the place, and some wasted oil. Never again will I let someone help me do my oil. |

I remember when a tech at the local Land Rover shop did an oil change on an 97 Discovery and forgot to add oil back into the engine. Pregant lady gets a few blocks down the road, engine siezes. $$$ I really have to question folks who motor on down the road like that with no oil pressure. I mean, don't get me wrong, the guy who forgot the oil should be drawn and quartered, but really, engines just don't cruise around happily and quietly for long with no oil pressure, and even the sorriest cars out there have bright red warning lights in the instrument cluster for low/no oil pressure. There's gonna be *some* kind of indication that something is amiss. I genuinely believe that the vast majority of folks who drive away from Jiffy Boob or wherever with no oil know full and damn well that their car is about to blow up, and they say "Fuck it, they're buying me an engine" and they stomp the go-pedal to the floor until it quits. |
I was in a rush a few months back and stopped at Wally World and grabbed some oil and a filter, a Fram filter. My last Fram by the way, I usually only buy Motorcraft. Three months later I change the oil, put the new filter on and start it up, oil sprays all over my dads garage. The seal from the old filter was stuck on the block. What a freaking mess.

As a younger lad I had a '79 yamaha triple 750 that I performed an oil change on. I pulled the filter cap and plug and let the oil drain, added the spec amount of oil. buttoned it up, started it up and went for a short drive. I learned a valuable lesson that day as I approached road speed, the oil spec includes the amount of oil in the shaft drive and, if that is not all drained as well, you blow out your rings and have an embarrasing slow ride home while being followed by a cloud of white smoke.

There's gonna be *some* kind of indication that something is amiss. About a month ago I did something like that at work. I'd been in the middle of a PM on a Ground Power Unit and got into something else while I was waiting for Piedmont Airlines to send me a load bank so I could check output and adjust the governor & regulator. About a week later it showed up so I started up the GPU outside the shop and let it run at idle til it reached operating temp. I was in the shop doing something else when I started hearing a ticking. I shut it down and immediately knew what had happened - I'd been waiting for the filters to come from NAPA and had never put the oil in. 5 quarts went in and the ticking was gone when I re-started it. Rule #1, look at the fucking oil pressure gauge when starting an engine, and rule #2, if you're not going to put the oil in right away don't put the filter on either, and vice versa. |

How about this?

Do a pressure test to check for leaks. Or hold a mirror or piece of glass under the exhaust, coolant vapor in concentrations too low to make visible white smoke or steam will fog the mirror. ummm...you know one of the by-products of combustion is H2O don't you? |
