What oil to use in AU falcon 4.0L

skyline_guy_r34, May 18, 7:14pm
Book recommends 5/30. Car has done 199kms, and it is used for towing 1500kgs 1 one weekend every month. No leaks anywhere, Not sure what oil is in it at the moment, all I know is its 2 years old. Is there any good weight of oil I should look at using! can only find fully synthetics in 5/30. Would be happy if theres a magic oil for these engines that is under $50 for 5 litres. Cheers

Use Castrol Magnatec, I've been using it in mine for years, it's also what a lot of Ford Dealers use.

the 15/40! Thats a few weights difference than 5/30. And thats a bugger as its 4 litres and I need 5. Ill wait for fish to come in hopefully that'll support someones answer.

To be honest, in an AU that's done 200k, I wouldn't worry too much. As long as you keep changing what ever you use.

What ever is on special usually works for me, normally 15/30 or 15/40 from memory.

Super cheap had a special on 10L packs a while back. which got me sorted.

Yeah I would have guess generic brand 15-40 based on the age. They're not an especially picky engine are they! Fairly low strung and all that.

Happy to be corrected.

I think you should go for a 10 or 15w-40 considering the mileage. The 40 weight should be ok and yeah I don't think they are a picky engine. I use Amsoil 5W-40 full synthetic in my BF XR6 and swear by it.

All suitable, under $50 and come in a 5L pack or more:)

Perfect mine has 199kms too and I wanted to know this too.

Penrite HPR15 works great. I use it in my 5L.

jasongroves, May 19, 2:58am
Out of interest, why do you suggest fully synthetic!

jasongroves, May 19, 3:06am
Theres plenty of suitable semi-synthetics available for cheaper:

This would be my pick for the price if going for a semi-syn:

That Valvoline oil is good as per jasongrooves, 5 litrefor under 40 buck. Handy for top ups as well and cheap but good quality. Semi synthetic is fine.

Why waste your time on synthetic oil in a 200k/10 year old car.
I use Valvoline 10litre trade packs from supercheap, $45. 10w 50. Change it every 5k, never misses a beat.

Just out of interest I wait for a Supercheap special and get Castrol Edge 5-30W for $50 for 5L (I need 8.4L so I get 2)

clark20, May 19, 2:25pm
One of the worst things with synthethic oil on old cars is that if it gets down the valve stems it burns on the valve, but it stays there, a lesser oil would burn off nearly completely, and starts build up that can only usually be removed manually.

I wouldn't use a full synthetic with those km's. Just use any generic mineral oil.

skyline_guy_r34, May 19, 4:09pm
Had a horrible experience using Engine armour 10-30 and then 10-40 in the ls1 I had previously. Put it down to being a picky engine. I GUESS I could try it again. Does towing affect which weight oil to use! Might pop in and grab that 5L 10-40 semi synthetic engine armour.

Valvoline 15/40 in 5ltr packs usually $40-50 at supersheep or ripco.

its an au use cheap oil, save your money for all the repairs to balljoints,brakes, radiator fan motors, power steering leak repairs and a new alt,radiator, and then more top and bottom ball joints,
as this model ate them,
I still have brand new ones in the garageshelf left over from servicing taxis ,
good luck
