I have afew things to ask.

How much does a normall cosworth engine use?

My car is a 89 2wd and has a metal piggtail handle on the dipstick. How many ML's is it from the max to the min on the gauge? And is this dipstick ok?

The car has done 50kmiles, but was laid up for 10 years while the owner was getting divorced etc. Then is was driven a very small amount then sold to me and im now starting to drive it after keeping it over the winter months.
It seems to use more oil than i expected. I know they all use some oil. The car was on the Rolling Road afew weeks back and there were no signs of smoke out the back when the revs were going up. Only afew puffs etc when he lifted off throttle. The operator said this is normall and most cars smoke alot more than mine did. So im realy not sure where the oil is going.

Im not sure if the car being out of use for so long has cause problems with the oil consumption or not.

Thanks Bruce
