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...
Good-Carbuyer 1st 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 ? "L" is the manufacturers' recommendation to avoid issue like cavitation. Topping up higher than "H" level can result in "oil leakage on some engines" Should not have any oil level issue if we maintain between "L" and "H" Link to post Share on other sites More sharing options...
Angchug 3rd Gear August 3, 2012 Share August 3, 2012 Can some expert offer some advice for the following : I did a search and as per the Engine Oil Viscosity Chart for a tropical country like us we should be using 15w40 - 20w50. However I noticed in the forum most members recommend 0w30 - 5w40 range. Any special reason to choose such a cold temp range? Thank You Link to post Share on other sites More sharing options...
Torquemonster 1st Gear August 3, 2012 Share August 3, 2012 Engine oil should be filled closer to the full line, but never overfill the oil because if it's too high it will come into contact with the moving crankshaft and as a result it will get whipped up with air and form air bubbles, instead of circulating oil through the engine, it will circulate those air bubbles through your engine and not lubricate effectively.

Tainey Clutched August 7, 2012 Share August 7, 2012 "L" is the manufacturers' recommendation to avoid issue like cavitation. Topping up higher than "H" level can result in "oil leakage on some engines" Should not have any oil level issue if we maintain between "L" and "H" Its really a nice information and also important for everyone and me also.

Thank You Based on the average temperate of Singapore from 1965 to present... we can safely ignore the cold temp rating. Quality of manufacturer and oil change interval should be your main concern.

5936 1st Gear August 11, 2012 Share August 11, 2012 Before yanking out the dipstick, check that car is on LEVEL ground. The difference between full and 3/4 is only less than 1L and short scale on the dipstick for small engines, so some slopes can really affect real oil level readings.

Chucky2007 Turbocharged August 13, 2012 Share August 13, 2012 During my last servicing, I noticed that workshop may have overfilled.. In morning when cold, the oil level is above the F level... Should I go n drain off the engine oil? Or justnleave it for another 9500km until next servicing? Link to post Share on other sites More sharing options...

Should I go n drain off the engine oil? Or justnleave it for another 9500km until next servicing? If just 2-3mm above the F mark is O.K.,some cars may 'eat' some oil in 3-4 k km.

Adrianli Hypersonic August 14, 2012 Share August 14, 2012 Should remove the excess oil till 3/4 mark I disagree. When engine is cold and not started, oil level should be at H level or slightly above H level. When engine is running, the oil level will drop to between 3/4 to H level.

Should I go n drain off the engine oil? Or justnleave it for another 9500km until next servicing? w/s tends to fill up more than F level. Every time after servicing, I will DIY pump out the excess (about 0.5L). Too much engine oil is bad for the engine. The reason why they overfill is they are afraid that your engine eats oil, and come back to kpkb/top up. Link to post Share on other sites More sharing options...
Ghostrider 3rd Gear August 14, 2012 Share August 14, 2012 The first number actually means nothing much to us...as the coldest weather we encounter is a rainy morning temp of 22-25 degree. The more important is the number at the back which denotes the thickness of the oil. How thin of the oil depend on how well your engine seals are. But usually I would go for 40 grade.

Cba6p 1st Gear August 14, 2012 Share August 14, 2012 the right time to chk oil level is 5-10min after the engine is turned off, not in the morning. Link to post Share on other sites More sharing options...
TVT Supercharged August 14, 2012 Share August 14, 2012 I did my servicing last week. The mechanic didn't pour all the 4L of EO into the engine. I asked him why and he said my engine oil total capacity only 3.96L (as stated in the manual), so no need to put in 4L. I check the dipstick and it was showing at 3/4 mark level. I always tot the dipstick should be at the MAX level. So was my mechanic right? Anyone can advise? Link to post Share on other sites More sharing options...

5936 1st Gear August 14, 2012 Share August 14, 2012 for bigger heavy duty industrial diesel engines, some dipsticks came with 2 sets of readings. One side for cold reading and another side for taking readings while engine is still running on idling speed. For our petrol engines, its cold reading. ↡ Advertisement Link to post Share on other sites More sharing options...
