nissparts: If the disptick were sufficient for everyone you would not see the possibility of an engine being over-filled with oil, ever.
You would also not see countless links on the internetz with people asking how much oil they need to put into their cars.
That being said, it is not also impossible for 2 VW Passats of the same model years for example to have 2 different lengths of dipsticks.

nissparts: Yes but like I always do, you are also assuming everyone is car savvy or has the basic wherewithal to do simple stuff car wise.
If you tell a regular joe to focus on his dipstick in order to gauge exactly how much oil his engine needs, you will fail to take into account that in some cases, the user will need to wait for some time to let the oil settle and get an accurate reading on the stick. Once this is messed up, it's downhill from there.

Even worse still is the fact that my friend for example was not changing the oil himself o...his "trained" mechanic did the oil changes for several years and still managed to overfill by 2 litres.

So, the very first idea the user needs is what the oil capacity SHOULD be and work along those lines.
If you know from the beginning your vehicle's oil capacity is 3.5 litres, you would not buy 4 litres and 2 extra 1 litre bottles on your way to the mech to change your oil thereby encouraging Kasumu to apply logic that it must mean your vehicle needs 6 litres and you can also be sure Kasumu does not believe in dipsticks.

vitality22: @nissparts, thanks a million. Please could you help us do same for ATF oil?

nissparts: Almost 5 litres.
Very little difference between the I4 and V6 oil capacity for the EOD

nissparts: Erico, I doubt strongly that you read my response before responding

Ikenna351: Yes, not knowing your manufacturer's engine oil capacity is kind of dumb, but I don't rely on it while changing my engine oil.

My ZN3J which is 2.8 L/cc takes 6 litres of oil to get to maximum mark, according to the owners manual and workshop manual. But I don't just pour in 6 litres of oil while changing the oil and oil filter, because I don't fill up to the maximum mark. First, I would pour in 5 litres straight. I would wait for like 3 minutes for the oil to settle in the oil pan. Then, I would pull out the dipstick and check. Whatever I see on the dipstick would determine the next quantity of oil to pour in. Gradually, I would be topping, waiting, checking and topping till it get to a level on the dipstick I want to, usually between the minimum and maximum, but closer to the maximum level mark on the dipstick (but would top up if everything checks out ok after few days). Why? Because the first few days of oil change, I would like to know if the oil level would increase from where I left it on the dipstick. It helps me to know the state of my injection system; to know if the injection system is overfueling the engine, which will wash down the cylinders, dilute the oil and increase the level. Leaving the oil level at maximum mark on the dipstick will then cause excess oil in the engine or over gauge which will introduce its own problems to the engine. Its a mechanical method of knowing the state of my injection system, scan or no scan, symptoms or no symptoms.

If for some weird reasons one fails to look up for his engine's oil capacity, dipstick is enough to know. All I need to do is buy about 6 litres of oil. Remove the old oil and oil filter and then get to work. First, I will pour in about 3 litres, out of the 6 litres of oil purchased for the oil change. Wait for 3 minutes or so for the oil to settle in the oil pan and then check the dipstick. The dipstick will now help me gradually pour in the oil till it gets to the maximum mark or level on the dipstick that is ok. Whatever amount of oil remaining is enough to tell me how many litres of oil my engine takes to get to normal level on the dipstick. That remaining oil is not a waste, because there will be another oil change, thereby determining the litres of oil to buy to complete the amount of oil the engine needs.

There is nothing wrong in figuring out other ways of carrying checks or repairs other than how the car manufacturers asked us to do in their books. It's called "being practical". That's the message Nissparts was trying to pass across, I believe.

Ikenna.

nissparts: Zim, as you can see, my post was referring specifically to the EOD.
You are free to look up the specs

First important point to note, the fact an engine is huge does not necessarily imply it requires a lot of oil

erico2k2: Im sure I replief to this,was my post deletef?
The most accurate way to do the mesurement of the quantity of oil needed for ones car is via ur deep stick,the ammount on the user manual is overal capacity,so wen feeding oil to ur car after draining,use the dip stick to gauge it.Here in the Uk one of the first question the examiner ask U is how do U check your engin oil level.if ur answer is Check user manual Op its a fail.

ZIM DRILL:

it was for this statement

nissparts:

The Nissan quest engine is a 3.5 litre engine and requires less oil than the honda accord 2.4 litre engine

Siena:



And for those that fill their engines with oil during a service, then allow 3 minutes before checking the level on the dipstick, one important factor has been forgotten.

The oil filter!

The oil filter can take up to half a litre. If it's replaced during an oil service, when the oil is poured in, the oil filter remains empty. So the engine MUST be run for between 10 - 20 seconds, to allow the oil pump to fill the filter. Otherwise an engine with an oil capacity of 5 litres could have just 4,5 litres, if simply using the dipstick after a lube service, if the engine isn't run, then checked again.

This is why engine oil capacities are often quoted with, AND without oil filter replacement.

anton8410: Hi guys,
could you help me with engine capacity for my car as I cant find any info please.
car: nissan primera hatchback 2.2 sx dci
thank you

IdaraCHODB:


Very valid points there.

In addition based on experience with certain cars, users might even be well advised to exceed the specifications in the manual by no more than 1 litre if there was a design fault that did not allow the oil to return to the sump at extremely high speeds, a good example being Mazda MPV 2000 and 2001 models if they operated the vehicles at such high speeds or made turns at very high speeds as well
