checked engine oil to day was missing half litter is this normal

oil in car castrol edge 10w 60 full sinthetic is this right

I've just lost a engine from not checking the oil, I always drum it into my wife's head to check the oil. Turbo cars can use oil more than others so it depends on how long ago you checked it and how many miles you have done I'm sure Jony and Finn Drew etc will have specs of what is normal usage

ok.
2 months ago serviced car done about 800 mile since oil change lost half litter oil catch can empty

Does seem like a lot, the oil level must be done completely on the flat or the stick can lie!!

ok thanks iv look for leaks but cant see any

my old bugeye wagon was the same but got rid so never had chance to see what the problem was

Heavy oil usage can mean many things

Piston rings
Oil stem seals
Turbo on it's way
Just a greedy car.
Or just usage as per spec

ok thanks will keep and eye on it

If its a 2.5 then they do u abit of oil I think half a litre in 1000miles is about normal! But will also depend on the Mileage the engine has done!!

800 miles count yaself lucky my lass used the hawk last week and did 40 miles and used half oil on dipstick

I know when I had my first impreza back in 2005 andy forest advised me about it being fully flat before checking and leaving the car to settle before checking, some think I always do as he's one of the best Subaru men out there

no probs car got 38k on clock will be keepen eye on oil fro now on thanks for all your help

as Andy G says, the 2.5 engines use a bit more oil, mine uses 1 litre to a 1000 miles. I use 10/60 as its modified a little bit but subaru recommend 10/40 on standard engines

done over 2000 miles in mine and its used none! and yes ive checked a few times

My 2.5 uses no oil at all, the 2.5 has tight piston clearances so seals very well, oil usage is usually a sign of a piston ring/ ring land problem.

yours and perils still have the standard pistons, its only when I went fully forged that mine started using oil, but I think most/all 2.5 that have forge pistons use a little oil.

Clearances will probably play the most part there and how safe you want to run it. Not physically what pistons you use. Running higher boost you'll run larger clearances to allow for the extra expansion of the piston with the higher temps etc.

So will this be the reason why mine burns so much if it was built for 500bhp and apperantly ran somewhere near that and now its at 350bhp the pistons arnt expanding the same as the should at 500 so the clearances are out? Just trying to get me head around it lol I no it will have to come to bits to find out properly, is it ok to just keep putting oil in for now even tho it uses a litre of oil every 100 miles ?

1 litre to ever 100 miles I think that is excessive.

ten litres to every 1000 miles is a little excessive to say the least

Sorry that was ment to be 200 miles a litre but not far off 100 when my lass uses it stop starting and it not getting warmed up properly on long drives it not that bad but I've used 5 litres full tub and done nearly 1100 miles

Try upping the power to close to 500 lee c if the pistons expand then and stop it using oil!
Who built the engine again lee ive forgot?

Pmsl that's wot a was thinking instead of rebuilding I'll just up the power

An epic company built it pmsl
