Was informed that these engines hold 30 qts. of oil and is dumped every run . Is there merit to this information ??

Since they get rebuilt after every run, I would think they would get fresh oil as well, don't know about the 30qts.

More than likely some sort of synthetic. Way, way, more advanced than automotive motor oil. As for dumping after every race? I wouldn’t doubt it, with engine rebuild after every race, and the desire to squeeze every available hp from the engine, there may not be an oil cooler, very minimal oil pump, running at very high temps, etc. So fresh oil for the very run, is not unimaginable.

I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science.

the cost of 30qts of new oil is NOTHING compared to destroying an engine using used oil that has 1 sliver of steel from a previous run....

TBH
These engines are configured quite different from other engines. Yes dry sump but only 12 Qts on average. No cooling system as do not need where the massive flow of air and alcohol does act to cool them Engine only has two rings, oil control and a compression changed every tear down which leads to oil itself. Most use a basic 70 wt oil, clearances in the engine are not designed for longevity but duration of race. Oil becomes so alcohol diluted during a run it has to be discarded, as the injection system floods the cylinders with the fuel much of which gets past the rings. They are far from economical as consume some four to five gallons of Nitromethane Methanol fuel for a quarter mile. |

If you ever get to attend an NHRA event, just set in the pits next to one of the teams and watch what they do between runs...Most impressive...especially when the rebuild is complete and they fire the engine up on gasoline for few seconds until the nitro-methane gets ignited...dang, earplugs and respirators help. BBRRUUMMP. Watching videos is never good enough to experience verses in person. My son works for a company that sponsored Brittney Force's top fuel dragster, I got to stand right behind that monster on the starting line during qualifying run. Nothing compares to that launch. Period.

Setting in the grandstands at Top Fuel event is ridiculous (in a good way). I cant imagine being at the starting line.

Never been to a top fuel drag event. But, I can remember the first tractor pull I went to at Bowling Green, OH and the Ohio State Fair! Similar awakening to having "seen" it on TV I'm sure. Even the time 43 cars came by me at 200mph as I was walking by the fence! Some things the ol' TV doesn't do justice for sure!

The motor is pretty much tearing itself apart in that run. I would almost bet the oil is shot.
Ok so the pullers must do the same

There used to be a IHRA sanctioned track on part of the old air base at Scribner NE. Once a year, the top fuel dragsters would be there. Always amazed my how when those cars would go by, my fountain pop would fizz over the top, just from the vibrations.

I used to change the oil on my dirt cars every other week. 7quarts.
I also changed back and right front tires every week or every other at the least. I bought Hoosier 970’s by the pickup load. Imagine all the tires used up in a NASCAR weekend. I think I read once that cup averages 400 Goodyears a week??? |

Thank you for the clarification of "quantity" of the oil, I knew it was a separate sump, and my friend said it was due to MAJOR fuel contamination as well as metal pollution during runs

I believe you’d be correct. There are 160 on the ground at any given time not counting backup cars. |

Lou I just did a quick search. Cup is allowed 15 sets of tires per team for the Daytona 500. That would be 2400 for that weekend just the cup teams.👀 |

I thought I read somewhere those top fuel dragsters burn like 12 to 15 gallons of fuel in their 1/4-mile run.

Back in the late 1970's I was in the Marines and was stationed near the old Orange County International Raceway (now defunct) in southern California. My buddies and I regularly attended the drag races there and at that time it was easy to get into the pits to watch the race crews.
There were mostly Keith Black and Donovan hemi engines being used at that time; those engines have the entire bottom end designed as one piece, what would be the oil pan has the main bearing caps built into it as a large, sturdy framework. When they drained the oil out it was a nasty, yellowish, stinky mess from the nitro-methane contamination after just one pass down the strip. Using air tools they could pull the "oil pan" in less than a minute; back then they didn't always pull the pistons and heads every run but I believe they may do that nowadays, I haven't really kept up with the craft in recent years. ET's were in the low 6's then with the fastest cars breaking into the high 5's. I understand they are quite a bit quicker than that now. |
