Changed my oil, it was filthy!

[mjhpadi]

Not suggesting this in any way, shape, or form...but I remember when I was a kid, I had a friend whose father would always drain the oil and filter, put the old filter back on the car. Then put kerosene in the crankcase, run the engine for about 45 seconds and drain the kerosene. then put on new filter and new oil. He swore this helped clean out the engine from the old oil and build-up. I have no idea if it hurt the car, but I don't ever remember them having their car in for an major engine repairs, and they kept their vehicles for long periods (5-10 years) before trading.

You can put a drop of oil on a white napkin. As the oil spreads out and is absorbed the actual dirt particles drop out and are easy to see. If it is just carbon and no particles can be seen then it is normal.

Wow, people come up with some crazy ideas! Look at your watch, 45 seconds is a long time, maybe turning it over a few seconds. I'd be afraid to run the engine, kerosene is like JP4. I know, you were only passing it along, but if the cars lasted them, I guess it didn't hurt the motor as much as I would think it would.

I've used a couple quarts of transmission fluid in place of engine oil for a similar purpose before. Not regularly, but if a car came in with really thick oil, the transmission fluid would act as a solvent and soften up the old oil and sludge. Run it until the dipstick indicated the fluid was pretty thin again, then drain it out, change the filter, and fill with the proper amount of the correct oil.

I've done that to try and clean a clogged lifter. It never worked. It probably helped to clean out the motor some. I had a Jeep in my younger days that I filled up with kerosene right to the head to clean it out, but I never started it. I just let it soak.

When I worked at an industrial complex, I bought one of their old yard trucks that was never licenced. Very low mileage vehicle but the crew idled it all night during the winter so they wouldn't catch a chill when they went out to do something. I drained the oil and filled it with diesel fuel and idled it long enough to get it up to temperature, then drained the diesel. Never hurt a thing, and the motor is still running (1980 GMC 305).

But back to the issue.
Would anyone consider running regular oil and changing it way more often? Or does the high heat turbo cooling prohibit that option?

X2 for synthetic always coming out dirtier than regular oil..

I've filled the crank case with diesel before after doing a valve job or swapping intake manifolds, etc. The oil pressure is normal, it doesn't rattle or anything abnormal. It doesn't hurt a thing to run it at a fast idle and get it good and warm, and it does clean out the engine out pretty well.

Thanks for all the input! :thankyou: At this point, I'm going to change the oil again after 1000-2000 miles and then keep an eye on it. I've asked the mechanics at my dealer to keep an eye out for any SHO oil changes they do. I'll let you know what happens.

I am getting my first oil change (a freebie) at the dealer next week. They use Motorcraft Syn Blend, but after that I will be changing to a full synthetic. However, I change oil and filter every 3000 miles or 120 days whichever occurs first. I honestly don't believe that it makes a difference between synthetic or conventional oil if doing regular changes. I also checked the owners manual and I didn't see a recommendation for synthetic or conventional oil...the manual only stresses using 5W-20 weight oil.

I look at it like this. If i'm spending $45k on a forced induction car, I am going to put full synthetic oil in it. It might cost more money, but I could have saved money by buying an sel or limited. Why cheap out on the most important fluid that is in your car?

I totally agree with your thinking!

You do need the engine to break in first. The rings need to seat. After the break in period is over then switch to full synthetic. And Ford now recommends 5W30 synthetic. So use that.
