How long does race oil last?
- Thread starter oil pan 4
- Start date
Race oils typically omitted detergents and dispersants to allow the anti wear additives to be able to do the most work in the short time they'll be used. The dda can interfere with awa, but most now have some dd additives just not much. It really depends because one could be called a race oil yet it's still a normal euro oil with euro approvals for long drains and some race oils are actually for short length racing.

Depends on the kind of race!

Depends on oil. We have several UOA of Motul 300V and it does good for 5k.
New 300V is more street "friendly." Wait couple of months and I will have UOA.

3.6-3.7 seconds
Plus staging and burnout.
Or if you remember the Pro Stock bike @RDY4WAR (IIRC) told us about, it didn’t have any oil at all and made two full 6-second passes and burnouts and survived thanks to HPL’s film strength and protective additives!
Could have made a third pass with Petro-Canada Duron.Or if you remember the Pro Stock bike @RDY4WAR (IIRC) told us about, it didn’t have any oil at all and made two full 6-second passes and burnouts and survived thanks to HPL’s film strength and protective additives!
First 300 mph, first in the 4s, both with Mallory magnetos and 113 LSA camshaft’s instead of the classic 108s.
Plus warm-up if being pedantic. But those are done at a small fraction of available power, so very little load on the engine, and very little fuel dilution.
Hard on spark plugs? Start off at .012-.016” and end the race with no visible electrode at all .
It is interesting..............take an engine that you can see in the oil fill port or are willing to pop open.
Fill with most any TRUE race oil. Drive around town for half year or 10K miles or 5238 miles.........
Examine inside of engine. There will be deposits. Deposits any street oil would have dealt with.

The condition of the electrodes after a pass, will depend on how close the tuning was for the prevailing conditions. Get it right, and the electrodes will be intact.

I would be curious to see that story. Curious experiment or big whoops?
There was a race way back when Kenny Bernstein ran dragsters, late 90s probably, where they forgot to put oil in it. They fired it up and did the burnout with no oil pressure. While it didn't blow up, they chose not to make the pass, but it didn't blow up with just oil film. Not full power, but still a pretty volatile situation.

Or when Walmart only put 2 quarts of M1 in BiL’s SBC - two weeks later he checked it before a road trip and needed 3 quarts …
Told him he needed to turn down that loud stereo once in a while …
It must have been that magical ProLong engine treatment that they used back in the day!
We had a situation at work, we have an Express van with a 4.3 in it.
I rarely drive it but needed to a couple weeks ago. Went around a turn and the oil pressure light came on
I had to go to HD anyways, so I grabbed 3 quarts of oil. Took almost all three, the **** engine only holds 4.5.
We've changed how we manage checking the oil lol
That's a story that's hard to believe. When warming it up in the pits, or when starting on the line, one of the first things is to verify oil pressure. The guys on the teams are highly qualified professionals, so forgetting oil is unlikely. If the lack of oil pressure in the pit was missed (highly unlikely) Kenny wouldn't have done a burnout with no oil pressure.
A pic of the Bud car back in the day:
Looks like HPL forgot to lock their lab one night....
"The oxidation onset happens about twice as fast with the mobil1 race oils"
"Race oil shear stability can be really good or not depending on the oil"
So it seems change race oil about twice as often as you would street oil, 3,000miles at the most.
