Hi guys i was looking back on threads to do with oil and im just about to do my first oil change on the AU. Now the book specifies 5 w 30 im sure but i brought some synthetic 10 w 40. Whats the outcome if i put this in the motor more or less wear etc. I would like anyones comments on the oil that they put in there AU and problems with certain oils.
Top Ghia, its strange that the AU II and Au III changed to 10w - 30 i think. But i dont think there was mechanical changes between the models i mean im sure the engines are the same.
It was changed from 5w-30 to 10w-30 due to oil consumption & Ford recommend 10w-30 in AU series 1 also. 10w-40 will also be fine. Ford have done long term tests with different viscosities & found not much wear in the engines regardless of viscosity.
so the HMAS AUI classic needs some lovin steve! i am just about to do a service on mine and ive always used Penrite oil I have 5 w 40 sitting in my garage to do it this weekend. Along with some breathing mods (T series snorkel K&N and all that stuff. yay for me!)
Dazza you crack me up mate. I have Grill going in and BMC Filter cant ****ing wait .
Thanks guys i will wack the 10 w 40 in with new filter.
Your never going to let the old Boar thing down even ifl i get her lowered. I can handle it hhaha
I didn't see your second post on it being duel fuel. You really should use a special LPG formulated oil, I use Penrite HPR gas, I think it is 20w-60, you need the higher hot viscosity because LPG motors generally run hotter.
If you want something lighter, Castrol Gas Oil is 15W-40, I use that in winter.
Also run about 20L petrol a month to keep your injectors and valves schmicko.
...Shame holdens cant say the same about the GEN III's
funny enough, most ford 6's seem to live upto at least 1/2 a million k's and not use much oil, provided they are driven in an 'ordinary' fashion.
Its not uncommon to see the old 250 crossflows lasting upto 800 - 900 000 kms
Compare that to the rattly GM V6, or a smokey red or blue, those things would be battling to see 250,000 kms.
On one of my taxis' (about 600 000 Km, early 99 AU) it has developed bottom end noise. Most of the people that I have spoken to suggest that the oil I used was too thin ( 15w-50 ).
i was thinking that maybe I should move it up to 20w 50 or would it be better to go for somthing higher? And no I don't want to rebuild the motor or replace the motor, it's only a taxi and I feel sorry for the poor bugger who is gonna buy it. Although it won't be the first car I've sold with bottem end noise (crank moved )

I think the requirements for taxis may be different to normal engines. Taxi's spend a large portion of their life running, so there is less requirement for oils that provide startup protection.
There is proberly nothing wrong with it per say.I just find there is a lot of bullshit concerning LPG when in fact LPG is better than petrol and the car makers spend heaps on developing motors and most of the time their recommendation concerning oil is right and if the so-called LPG oils were needed why don't the Ford dealers use them,simple answer not required and just sales hype.There are a number of articles writen about the dangers of running a thick oil in a motor made for a Lo-viscosity oil,I can't remember all the details but its better to err on the side of caution.
I think I will stick with the LPG oil, horses for courses I suppose.
That LPG oil has a "low ash" formula (whatever that means) and extra additives to neutralise combustion by-products from the gas (whatever they are).
I'll have to take their word for it. Castrol Gas oil is only $20 for 5 litres, so it's not too expensive.
cheers
