Drinking Oil

[Radion]

Hi Gurus,

Sorry if this has been covered, but I have searched the interwebs and cannot find any answers.

I did a service on my R33 Series 2 about 3000kms ago with K&N oil filter and Motul 5w40 full synthetic.

I checked the oil level on the dip stick this morning and the oil was already on the low level. There are no leaks that i can see on the engine itself or under the car and i park the car in 2 same locations everyday so it would be visible if it was leaking from under the car.

What could this mean ? or is it normal for skylines to drink oil ?

I understand that its normal for old cars to drink oil but my r33 has only 123,000kms and full service logs and has been stock its whole life.

Cheers

Did you check it warm or cold?

Hey mate, I checked it when engine was cold on a level surface in my garage.

well it has to be going somewhere... and thats alot of oil for it to 'drink' in that distance...

a car shouldnt lose any oil really if all is right... mine never does...

[Radion]

yeah has to be going somewhere, but there is no signs of leakage ?

I filled it to the top so about 4.3 litres, the car is standard except for exhaust and pod filter

If you filled to the hot mark while cold, the difference is probably sitting inside your oil filter now.

[Radion]

So would it be good to check it when the engine is warmed up ?

On an oil change I always fill so that it ends up sitting on the high (hot) mark AFTER the car has fully recirculated the oil.

This means you can then very easily see if the oil were to drop for any reason during service intervals. Mine never does but if the day comes when i do ill know straight away.

Rb's also seem to be a bit safer with a higher oil level, especially if you give them some revs n cornering...

i would put 5 litres into it, not 4.3

bingo.

and just a random bit of trivia to make all us RB owners feel better about the amount of oil we need to feed our beasts. Particularly modified RB26's

- The Lamborghini Aventador needs 13 litres of what im sure is some pretty top of the line fully syn

WOW 13 litres haha

When i put in the full 5 litres my oil pressure was going all over the place so i drained it down to 4.3

[SiR_RB]

put 5 litres in, start it for afew mins, then let it sit for 10mins for so and recheck level, should be on the H mark once the oil has filled the oil filter

[Radion]

I just rechecked it this morning and the level seems to be at the same level as when i filled it up(hasn't dropped). I also checked the radiator for oil and it seams to be clear.

I must have checked on a very slight angle, i have read somewhere that on a skyline even the slightest angle makes a huge difference to the reading.

Thx for all the replies.

sitting on the high (hot) mark

It's H for HIGH, not H for HOT.

If you replace the oil filter at the same time as you do an oil change, you need to put most of the oil in and run the engine for a few seconds before checking the oil level in the sump. Then add oil to bring the level up to the H mark.

The difference between high and low on the dipstick isn't huge, about 1 litre or so.

333ml per 1000km isn't the end of the world, especially running 5W40.

[RadoGTR]

My tuner recommended 15w50 for my engine (and any other rb) when I was using 5w40, he said that when pushed a bit harder, it will just drink it, will become to thin

dont forget the weather will affect what grade of oil you should run, slightly thinner for winter, slightly thicker for summer
