Very interesting!...Ute is a pickup?...25w-60...I bet Aussie cars go just as long as American cars...Do they even have 5w20?...if they do they probably use it to fix squeaky door hinges!

Aussies give me the courage to consider 10w40!...My father, who lives in Florida, would love to get his hands on some of these weights...well as long as they were Valvoline oils...Quaker State and Pennzoil cause sludge

Haven't introduced him to Bitog...in fact not sure if he has ever been on internet...Okay I need to check out Valvoline Australia...
 
20W-50 was the only oil (bar 30 diesel oil) for decades...All OEMs specified it. Shell introduced 20W-40 in the late 70s, early 80s. Introduced 15W-30 (XMO) in the mid 80s, and were attributed with engine failures.

Our engines lasted longer. 200,000 km, and if the engine consumed 1litre/5,000km, it was considered time for a rebuild. 1 litre per 1,600 km, and you'd think the car was going to die (not brand new).

Lowest I've gone is 10W-30. Have used straight 30 in a few diesels...never seen a 20W
 
I find it particularly entertaining that oil viscosities are geo-politically recommended. I even have some issues with SOME climate recommendations (as in it gets darn straight as hot in So Cal, AZ, Tex, the deep south, etc as it does in Oz).

I guess the good news is that we can use oils that don't rob power and bog the engine with the same or, actually better, wear results. I mean I went from a 10 cSt 30 to a SYNTHETIC 40 at around 15 cSt and man, the feeling is there. The car got such excellent wear with the 30, so why bog it with a 40? ..... You guys down under are more confused than us.

And that's scary because we are being hoodwinked by the environazi clan.
 
i find it interesting that in america my honda is speced for 5w20 year round. in australia it is speced for 10w40 and 15w40.
for my ford which is speced for a 5w20 in america, 10w30 is speced for australia.
for my dodge bcar its 5w30 in ameirca. 10w40 and 15w40 in aistalia.

funny i use 15w40 in everything i own. i dont think my honda is gonna blow anytime soon.

That's because the Hondas they ship to Australia have looser engines to handle the thicker oil.

Remove the goverment/enviro regulations and oil selections may look similar. How much proof does anyone need that the 5w20 is a conservation gimmick. If it was overall better for your engine, then why doesnt it have global acceptance?
 
I think the difference may also be due to driving conditions not only temperatures. Here is the US we spend lots of time driving 4mph. Our highways are not high speed, this may also play into account.
 
Like Europe, the aussies have longer OCIs than us standard, although synthetics aren't required. Seems that thicker oils are recommended more often for longer drains - less chance of thinning, fuel dilution, etc.

I'd like to know what oil is specified for my Mazda CX7 turbo engine.




MOBIL 1 10W-30 or MOBIL SUPER FE SPECIAL 5W-30 (from mobil)

5W-40 (HPR 5) by penrite
 
Ok, so are the engines actually different from country to country? For example, my 2005 Ford 5.4 motor...is it the exact same motor that's used in Australia?? And if so, why is a 20w50 recommended over there?? Some say it's because other countries don't have CAFE to deal with, while others will say that the newer motors have tighter tolerances and NEED a thinner oil... Which one is it???

No. Just the availability of certain weights of lubricants, and their resulting marketing/information campaign to reassure them that it's "okay" to use a thinner oil...

Actually, I thought someone posted it was Mobil1 0W-40 that was "preferred" in a 5.4L, after a break in period...
 
It would be nice to see the UOA's on some cars from down under. Then compare them with the same engines here.

Assuming they run the same oil brand but thicker etc...

That would answer some questions if we could gather enough data. Then again, the oil goes down the funnel counter-clockwise there.

It would also be interesting to know how much of a MPG hit they take, using significantly heavier oils... IF UOA's show that, say, a 20w50 and a 5w20 provide the same protection, but the 5w20 gets 10% better fuel economy, then that may make a big difference in one's deciding what oil to go with.
