Hey all, I have a peculiar problem. I have a 2000 Audi 2.7t.
The car has been parked for 9 months and has not been started for at least 6. Anyhow I got back in the country and checked the dipstick and it was bone dry (no oil leaking on the ground). I was told it prob sludged up and i should use seafoam. Well i bought the seafoam how should i go about this clensing process for my model and are there any other suggestions before i try to crank her up.




Thanks in advance

 

I think I would drain the oil from the crankcase, then re-fill it with new and then start it. If you want to use Seafoam after that, go for it.

 

That doesn't make any sense at all. Sludge is just carbon and dirt that gets stuck to the engine walls. It's not sludge at all looks gritty. But it's not where your oil went.

Did it have oil in it when you left? probably not.

Anyhow fill the crank case with oil again and add 1/2 bottle of seafoam drive around for 30 minutes allow the engine to cool and then change the oil and oil filter.

You should use a cheaper oil to re-fill and flush like penzoil or what ever because your going just throw it out anyway. then refill with Mobil 1 synthetic or castrol synthetic.

 

Oil just does not disappear without leaving a trace. And if you used full synthetic, it doesn't turn to sludge, or anything else, on it's own. I've stored Crossfires for 6 months and all the oil is there in the spring. Now it's possible some did leak out -- do you have a belly pan and is it pooled on that? Otherwise I would slowly refill to the center of the dipstick mark (between empty and full) before starting it. If you used dinosaur oil, it makes sense to change it. If it was full synthetic, I'd drive it since that stuff does not break down as quickly.

 

Oil dosen't just disappear unless it is leaking. 6 months or 6 years should make no difference.

I would pull the drain plug to remove what ever is left and replace the filter. Be sure to fill it with oil before putting the new filter back on and fill the crackcase with decent oil. Run the vehicle for about 100 miles then change the oil and filter again.

 

You guys atre right , a few months back i did some type of fluid(not water) on the ground near the drivers side front fender near the bumber, however it was almost dark and because I was catching a flight I did not have time to inspect and I was gone for 3 weeks.
