Treating Oil on a wet Track? (merged with 'Oil on the track')

Having yesterday been at Donnington on Post 4. The Fact are:

Second from last race cars set off on the green flag lap a Jaguar throws a rod through the engine block at Post 1 drives around to Post 6 on the outside line. Oil now laying on top of a wet track in places. Circuit staff turn out with a pressure washer and detergent to treat the oil. We Marshals treated the dry sections of track in the normal way. No problem at the start of the race slight traction problems for the second drives (I forgot to say it was a two drive race).

Last race no drives told about the oil at Redgate Gravel Trap becoming a car park with four cars including one roller (ended back on wheels).

Walking on the washed section of track at the end of the day was like walking on ice.

So how do you treat oil on a wet track?

Sounds like they were using either too much detergent or not enough!!!!
It,s always a do you or don,t you thing treating a wet track but i wont use cement or the equivalent on a wet track cos you can make it worse. the pressure washer idea sounds good but you,ve got to get it right.

For bikes we use washing up liquid, a pressure washer and a hell of a lot of elbow grease - the trick is to ensure that the track is brushed into extinction!

Having said that, I think it also depends on the drainage on the track. Mondello slopes a fair bit, so we can usually persuade it to run into the gutters.

The best option has to be the oil "nappies" which pretty much work in all conditions - but they're expensive and no-one wants to use them

Oil Slicks

I was at Donington on monday, and it started raining. After it rained, one of the cars decided to drop oil around redgate, at least a foot wide in some places. As there was water on the track it was impossible to dress the oil with cement, but was too dangerous to race on so the circuit staff jet washed it with some detergent. It ended up being like a skating rink, the drivers in the 1st race after the spill were informed of the slippy track and adjusted there racing lines, the next set of drivers were not told so we there were about 5 cars in the gravel.
Any reccomendations on dressing oil in the wet as jet washing is clearly not the answer

Poor Jinx, can not read or remember what was said 24 hours ago. To quote you "if some one started a thread I'll add to it". So I started it.




Will you be at Cadwell on Sunday?

Have heard that Rockingham have some sort of special saw dust to mop up oil spills, does anyone know anything about that and would that work in the rain?
The track was dangerous at dono, the drivers kept insisting that there was still oil on the track a lot wider than the original slick

Speaking professionally as a geologist, vermiculite (type of clay) should work very well in this situation. As a driver, all I can say (race before that - Oldies But Goldies) it was flippin slippy when it rained - always is at Donington - I suspect that the rain brings down suspended AvGas from the takeoffs at East Midlands - I think it also brings it out of the tarmac - Mcleans was particularly bad this time (you can guess that I spun there ;-).

I was in the race when the clouds opened and in the race the Etype deposited its guts. I got it wrong both times as I was first driver in the rain race (so got the full brunt of it) and second driver in the other race
in the rain it was quite strange Redgate and Old Hairpin were undriveable (I spun into the gravel at Redgate but fortunately managed to back it out) but up the other end of the track it wasnt too bad (unlike SRS qualys onthe Sunday morning when it was deeply unpleasant all the way round! breaking up hill and locking up is a novel experience!!)
during the SS race I took over for the second half and the track was becoming more scary by the lap! Redgate braking zone was awful and the chicane was pretty nasty but the rest wasnt too bad. Apart from the slight mishap on the pace car on sundays SRS race as a driver I thought it was very well marshalled all weekend - thanks!

Jinx I know about the Rockingham stuff it is proper oil dry as used in industry. I had forgotten about Rockingham using this stuff. Now if my memory is correct they used to keep two grades of oil dry, fine on all the post and coarse in the clean up vehicles. There used to be oil dry mats as well and a chemical degreaser. All these where a requirement for the Indy cars.

The main different between this type of oil treatment and our normal plaster or cement is you only apply a little of the oil dry leave it to work for a short time then sweep it up and shovel it away for disposal. As for use in the wet I know some even soak up water and other chemicals.

Now to show you why all the knowledge we use the same stuff at work. The down sides are cost, training and disposal.
