That's the question. In the US, for example, Subaru's threshold's really high, so you have to be burning a ludicrous amount of oil per week (week!) before you qualify for a replacement short block. 1 Link to post Share on other sites More sharing options...

The same person who decides whether to say what is happening is normal or not. The point is, the statement is tautologous. 1 Link to post Share on other sites More sharing options...
Carnoob Supercharged July 8, 2016 Share July 8, 2016 I've learned NOT to believe any report or research 100%... they will write to the benefit of whoever SPONSORED their research... Look at COFFEE, BUTTER etc... One study says bad the other says good. If it ain't broken, don't fix it... Study can say this and that but most importantly, I'M HAPPY. 4 Link to post Share on other sites More sharing options...

Ahbengdriver 6th Gear July 8, 2016 Share July 8, 2016 (edited) usually its the valve seals that have hardened. Replace them and the oil loss will be stopped. I used to have a car that, after the 7th year, requires a quart of oil every 3000 km, then 2000 km then 1000km. Got the valves replaced and walah! for the next following 3 years until car was scrapped, the oil level needle remained steady poon pee pee.

inlinesix Supersonic July 11, 2016 Share July 11, 2016 Which car model n how much $ for the valve seals? Must be his BMW E90. Should be around $200. Link to post Share on other sites More sharing options...
Ahbengdriver 6th Gear July 14, 2016 Share July 14, 2016 Which car model n how much $ for the valve seals? My previous old lao-pok BMW E90 model. The valve seals and valve cover gasket should both be changed together. These things are actually very cheap although I cannot remember. Probably not more than $150. You just have to find a workshop to change it for you. or if you got balls, check out youtube and DIY. hi, can PM me where did u get the valves replaced and cost of it? my 250Kkm mileage car is consuming engine oil quite badly.....abt 2 qts for 5000KM...... Depends on what car n model you driving, but any car should have the similar parts which you can check out the stockists. That's not so bad, wait til you kena 1 litre oil every 750km. By then, you will feel like adding olive extra virgin oil into yr engine. Link to post Share on other sites More sharing options...
Tigershark1976 Turbocharged July 14, 2016 Share July 14, 2016 BMW must be joking....one quart of engine oil per 750 miles (almost 1 liter per 1000km) ? Their Engine is design to burn engine oil or fuel? Like that for 10K oil change interval, 9 over liters of engine oil is needed? Xiao bo? 12 Link to post Share on other sites More sharing options...

Ahbengdriver 6th Gear July 15, 2016 Share July 15, 2016 Many of us, used to, change cars after 3 to 5 years hence not many experienced this fully during car ownership. it is quite common as your car ages, that the valve seals will start to loose its tightness. Its common wear n tear. at first the loss of oil is slow but if you don't change the seals, the problem will slower get worse. Its common wear n tear. For the E90 model, most experience oil losses after 5 years onwards. Any other car could also have same issue. A friend's Merc S class 8 year old also need to top up 1 litre every 2 to 3k km. He doesn't want to repelace the seals bcos he is gonna change seals because he wants to change car next year. Also, I am no car expert but contrary to what many often refer to as "engine burn away the oil", my mechanics told me(and showed me) that what really happens is, due to the un-tight seals where the rubber had harden over time like our garden hoses, the engine oil sips into the combustion system n comes out at the other end of the exhaust as whitish smoke. the white smoke is the 'burnt' engine oil. 1 Link to post Share on other sites More sharing options...
Yeobh 4th Gear July 15, 2016 Share July 15, 2016 For shop equipped with this set of special cylinder head spring compressor , to change the valve stem seals, there is no need to remove the cylinder head. The task is make very simple and it's a time saver. 1 Link to post Share on other sites More sharing options...
Fuelsaver Supercharged July 15, 2016 Share July 15, 2016 Those who say its normal are either manufacturers or someone trying to sell you their car . take a look at this para quoted - [“Oil consumption is normal on all engines,” BMW spokesman Hector Arellano-Belloc said in an e-mailed statement. “BMW vehicles have long intervals between oil changes (10,000 miles). BMW engines (excluding the BMW M) may consume up to one quart of engine oil per 750 miles under certain driving conditions.” He added that BMW’s M performance models may consume even more oil than that.] if it's from a reputable maker it MUST be correct!!! btw, my >8yo hyundai tucson manual stated max top up eo at 1l per 1500km, but havin owned for >3yrs, i did not need a single top up and just before 10k km servicing, eo level still at max line. i hope it stays that way till scrap! ↡ Advertisement 1 Link to post Share on other sites More sharing options...
