Peztacular

Just about to do the first service on my fairmont ghia EL I/6 the car had the 140,000km service 5 months ago by Castle Hill Ford (where i bought it from) and i have now coming up on 145,000kms.

Now i want to know what oil i should use, im not sure what oil is in it at the moment but it has the typical falcon chatter coming the head (mind you its very very quiet and not really noticeable esp. compared to my NC fairlane)

what oil do YOU recommend? Synthetic or mineral
thanks for your help

Just go for a 15W40 (maybe even a bit thicker, summer coming and all) mineral based oil. The I6 has no specific querks about it. From memory it takes 4.5 litres with a new filter and 4 litres without filter.

Ive used 15w40, or 20w50 in mine for years.
I never use pure mineral oil.
i always use a semi synthetic, such as Helix plus, Havoline F3, or i am using Fuchs at the moment, its a very goo oil.

id go semi-synthetic too, u could also go 15w 50

Semi-synthetic (which most oils are these days) 10W40 or 15W40 and the engine will hold 5.5 litres with an oil filter.

I know a few guys that use a thicker oil & end up with noisey lifters.

I thought I better clarify; by thicker oil, I mean the Winter rating 10W, 15W. I've heard noisey hydraulics on engines with 25W & above in them.
10W60 and similar oils should be fine.

davowasere

ge you must know a thing or two about engines.. noisey lifter in a el?????? ohc?????

stick to the ford recommened oil motorcraft 15w-40 oil and you cant go wrong. anyone who says this oil is no good needs there head read. ford specify it for a reason. if you know anything about oils not all 15w-40 are the same ??? ask anyone who knows oils a distributer.

What are the advantages/disadvantages of using a thicker oil?

I know if the oil is too thin, it is like not having any oil at all. So the thicker the better, right? Thanks.

PS By the way, I've never (by myself) changed my oil before, but next time it needs a change I'll be doing it myself. How do you dispose of the old oil? I'm sure it can't be a good thing to go down the sink... Thanks.

The only real advantage of using thicker oil in an I6 is to shut the lifters up.
Its really only good if your car is going to cop a hard time all the time.
Ive done all sorts of motorsport withmy car on the old 15w40.
