Following this thread with interest as mine uses quite a bit of oil, although it has done 153k...so I'm happy to keep topping it up for the time being.

 

If it's 1l between the marks then ive used under 1l in 1100 miles which is in the tolerances isn't it?

Checked the oil filler tonight with engine running and no smoke at all and not breathing heavy.

 

Non of my cars ever went down a single drop mate

 

The reason i asked the mileage is as already now been said and that a starter point of 5 is too thin and maybe if suitable a 10 might be better.

 

On both my Impreza's i've had leaks, on the daily driver it was coming from the front oil seal ring. cheap to buy but cambelt will need to be removed. 2nd was rocker gaskets, you can smell the old burning on the exhaust manifold first thing in the morning.

 

Thanks for the reply. I'm going to my dads garage tomorrow to give it a good check over however I topped it up this morning and it took about .75 of a litre to get to the full so in 1100 ish miles I don't think is too bad really

 

Right so I now done 1200 miles since topping up and it hasn't used a single drop.

Very strange!

 

I think dip stick is .75 of a litre top to bottom , it's using a fair amount but according to Subaru it sounds like it's ok , it does depend on how it's driven, weirdly if you run it at the max level it seems to take longer to use oil , run it at the lower level it seems to use it faster , I would use a thicker oil any way a 10 or in my case a 15/50

 

Does sound about right when I serviced it I left it just under the max and it went to the low within around 1100 miles. I topped up to the max mark and it's still there after 1200 not moved at all

 

I would not worry too much , if it's driving ok and not kicking smoke out it sounds like it had a moment or when it was measured it was not in the same circumstances as normal , if there is no obvious leaks and it passes an mot then job done

 

Yeah it drives spot on and no smoke at all.

And like I say it hasn't used any oil at all in 1200 miles. Might have been a one of or sometbing.

I'll keep an eye on it.

Thanks mate

 

The rings on the Pistons apparently rotate which is normal ,they are not supposed to leave a gap but maybe yours did and that's why it's a one off , I think the combination of a bit of oil use plus a dipstick reading before that was not as normal then that was probably the problem , it all sounds fine so don't worry

 

Yeah I think ur right don't think there is a problem after all. Thanks for everybody's replies
