Mystery dipstick markings

[mariononslow20]

Here's a puzzle; 1098 engine with a dipstick that has 3 notches, min, max and sort of super-max. Which level should I fill to?

The engine was a recon unit fitted about 10 years ago if that sheds any light. Its just slightly unsettling that the max may not be enough[frame][/frame]

The picture isn't v good. The top notch above Max runs across the blade like the others, but looks like it has been added by using a hacksaw.

Measure from the collar (where it sits in the support tube) to each of the markings and report back, we can then compare with a standard dipstick and ascertain whether your markings are correct.

Collar to

Super Max 16.5mm
Max 19.3mm
Min 21.5mm

Collar being the rubber washer that sits on the top of the tube

Looks like the extra mark is just that. If it bothers you - no harm will come of running with the level half way between the two high marks. And next oil changhe - add the correct volume of oil, then after running the engine to circulate the oil, and a couple of minutes to settle - check where the oil sits and use that mark in future.

A picture of the whole dipstick will shed more light on what dipstick it is as there were several different types/lengths of dipstick fitted to the 'A' Series.

We have the answer, as bmecosse suggested I did a complete oil change and put the correct amount of oil in (6.5pints)

The level now comes to the original max mark, so I will ignore the other one

Thanks for your input
