Hi all,

I have tried to do servicing at several different workshops. Most of them says that the engine oil level must not be above the maximum level (at the engine oil level indicator).

During servicing, the mechanic always fill the oil filter at first than install it at the engine.

Now, I would like to ask you, for my engine, what is the maximum litres required? and what would be the minimum?

I've ask many workshops, I got many different answers: it is between 3.5l to 7l.

What is the average litres anyway?

rgds.
Ray.

Hi Dunsong, my 3.1 takes 6 litres with filter. The filter on a 3.1 is normally bigger than the ones on the 2.8 but otherwise these engines run the same block & share most vital dimensions with the 3.1 so I reckon you'll want about 5.5litres. Hoepfully someone else can help out on this one.

Definitely over 5 litres, I found my 2.8 took closer to 6 with a filter change.

Oh and its not possible to fill the filter before you put it on as its mounted with the open end downwards so it would be very messy if you tried it. Its a bit hard to get to I used an oil filter strap type wrench on a very long extension to undo itand you need a long thin arm to refit the new one. Theres also a drain bolt next to the filter that should be removed, the remaining oil will then drain out all over the exhaust (nice design feature!) there are three little rubber O rings that should come with the filter that will fit on the drain plug and need to be replaced each time. The best way to reach this is through the wheelarch under the rubber flap that you will find in there and again a long extension will help as will a wobble drive or universal joint as theres a couiple of brake pipes located just in the wrong place to get a straight shot at it (who designs these things eh!). Replace the filter and drain plug (and sump plug) refill to the line, fire the engine up briefly until the oil pressure light goes off, check the level and top up as neccesary.

I had a 4JB1-T 2.8 liters before. Without any filter change, it is less than 5 liter (couldn't quite remember.....probably around 4.5 or 4.8 liter). With filter change, it is 5 liter. You are definitely asking for trouble if you fill 7 liters.

Doing the above, you oil dipstick will show somewhere in the middle or the 2 holes. And whatever you do, you shouldn't fill oil that goes above the maximum hole on the dipstick. The top maximum hole is there for a purpose. If any mechanic should dispute that, ask them to pick up a dictionary and look up the meaning of the word "maximum".

On your mechanic. He is a very good mechanic to fill some oil into your oil filter before changing so you should hold on to him.

Putts pressure on the head gasket and other parts. If you find you have over filled it just let a bit out the bottom Wink
