Spiderman302 2nd Gear December 10, 2011 Share December 10, 2011 Can some expert offer some advice for the following : Must engine oil be filled up to the "full" level ? As the dip stick shows both "L" and "H" mark, theoretically 3/4 full should be ok right ? ↡ Advertisement Link to post Share on other sites More sharing options...

Nikelashi Neutral Newbie April 15, 2012 Share April 15, 2012 got the same issue, just recently changed engine oil, and there was a leak. only replace the gasket 2 weeks after servicing and the oil level currently is about 4/5. since i just serviced, that means i have another almost 10k to go before my next oil change. is it healthy for the engine to be running on a less than full EO?

Kangadrool Supersonic April 15, 2012 Share April 15, 2012 Most ws in Singapore will overfill your engine oil. Example, your engine needs 3.7L, your mech will empty the full 4L; your engine needs 4.8L, your mech will empty 5L inside. After every new oil change, I go home, use homemade pump DIY pump out 0.5L of engine oil, check oil level gum gum hor, at the upper mark. Too much engine oil is very bad for the engine.

Good-Carbuyer 1st Gear April 15, 2012 Share April 15, 2012 H level allows you to monitor any slight engine oil loss without risk of engine oil lubrication failure L level leaves you no room for such monitoring purpose So better fill to H level, for peace of mind Link to post Share on other sites More sharing options...
Yeobh 4th Gear April 15, 2012 Share April 15, 2012 In future get yr mech to use a measuring jar so that you need not have to pump out the excess oil. Link to post Share on other sites More sharing options...

As the dip stick shows both "L" and "H" mark, theoretically 3/4 full should be ok right ? Depend on what car you drive, if conti car that consume engine oil, Full or slightly more also ok. For Japanese or Korean car that doesn't consume oil, between 1/2 to 3/4 would be the best, if fill to full mark, engine would be sluggish. Link to post Share on other sites More sharing options...
Eng40765 1st Gear April 16, 2012 Share April 16, 2012 My workshop always fills half way between h and low mark, no issue at 150k km. my engine doesn't eat oil though....... Link to post Share on other sites More sharing options...
MrolexB 1st Gear April 16, 2012 Share April 16, 2012 I saw my WS pouring half or so, then use dip stick to check .. then pour again and check. Separately, how WS tell the level when refill ATF ? Especially for those models without ATF dip stick. Saw (again) my WS drain the old ATF, leaving it open, refill ATF until it flows out from opening ... then it put the screw back ... haha ... accurate mah ?

Yeobh 4th Gear April 16, 2012 Share April 16, 2012 (edited) ATF machines are expensive investment but t least your mech should have simple evacuation/ refilling hand pump so that the amount needed is carefully measured and inject into the transmission.

Caravan 5th Gear April 16, 2012 Share April 16, 2012 I always tell the workshop to fill up to 3/4 level only. Because I've got 2 bad experiences of overfilling (one at AD). The AD mechanic even show me that the 'correct' level of checking oil is to start the car engine and then check the oil immediately after stopping it. For NA car, actually 3/4 level is just fine. No need to be so kiasu to fill up to full, as it is easy to overshoot. Overfilling is just as bad as underfilling. Link to post Share on other sites More sharing options...

For auto transmission without a dip stick, the refill hole is usually at the side of the transmission and once full, excess ATF will flow out. example Edited April 17, 2012 by Trex101 Link to post Share on other sites More sharing options...
