Yes, in terms of oil quality for your dollar, these must be the two best buying oils in Oz. Both are SN & A3/B4, with the HX8 being full synthetic and the HX7 being a semi-synthetic.

I picked up 5L of HX7 10W-40 last week for $20 on sale.

Interesting article from last year

http://www.savantgroup.com/media/IOM-Art...Oil-Quality.pdf

Which then sends you to
http://www.instituteofmaterials.com/engine-oil-database/index-of-oils-tested/

Who buy off the shelf and test to death any number of engine oils, and produce reports like
http://www.instituteofmaterials.com/wp-content/uploads/2014-Primary-Report-Sample.pdf

I wonder if a subscription would count as a tax deduction...



That would be interesting, but I couldn't get a tax deduction for that

Notice that all the oils I listed have a low KV for their HTHS rating aswell. We're on the same page, or very close...

Penrite is like unobtanium here, and Castrol is THE most expensive oil on the shelves. 132 euro for 5 litres edge is going price.

The others I listed are about 1/5th of that, and are available in A3B4 with edge only in C3 (30 weights)
 
xtel, mentioned 0W20 Petro-Canuck supreme synthetic, here is the 5w20 example:

40C 45
100C 8.3
HTHS 2.7

By mixing SAE 10W and SAE 30: 50/50

40C 55
100C 8.3
HTHS 2.9

SAE 10W 70%
SAE 30 30%

40C 45
100C 7.5
HTHS 2.7

Mono-grade flash points and density averaged higher than 5w20 in all examples.

There are probably more oils we can't get than you can, and far cheaper, being further away from where oil is made than most countries. Castrol is failry cheap here, but top end oils also fetch top end prices. I'm used to shopping at the supermarket only looking at the bottom shelves....so don't look up at the top shelves for oil either. There is usually something very, very good for a pretty good price.

We no longer get BP oils in NZ, maybe BP is supplying us with Castrol oils across a broader price range.

$6 something a quart is still cheaper than Amazon - and way cheaper than NAPA's $9 something a quart; but a 5 quart jug under $25 would be closer to affordability. I'd still have to buy the 6th quart for top offs.

If that would allow Walmart to sell more oil and/or make more money, then they would have done so already.

xtell: You might be able to find a distributor down there. The U.S. head office is in Chicago, I believe.

Having said that:

Have you experience with it personally?

What do you favor if not Redline?
 
Penrite 50w70 but more because of the fact that anybody would use that in an engine with out clearances of half an inch, although i posted a thread and one person said they used this in their Mk2 Ford Escort which would have been specced for 10w40 to 20w50, in order to control massive oil burning

Agreed. In the synthetic realm, I would wager that M1 is the top seller at WM.

Ours doesn't keep it (Delo 400 SD 15w30) out front so I have to ask them to get it from their inventory in the back. FYI.

Yes I used Redline 10w30 and Redine 10w-40 in my Holden Commodore V6 3800 1995 engine.

I did 2 used oil analysis resulting high iron, silcon and tin in consultation with the Perth Redline distributor in 1999/2000. The Redline distributor actually paid for the 2nd UOA however he never gave me the results of the 10w-40 compared to the 10w30.

After repeated calls which were never returned I gave up and switched back to Mobil 1 5w-50 after which I ended up with minor oils weeps around various parts of the engine. The engine never weeped any oil prior to the Redline.

It is assumed that the high esters in the REDLINE OVERSWELLED the engine seals and these never recovered when I used the Mobil 1.

The Redline Oil in those days was $14/ L AUD trade compared to $28 /L AUD now days Trade.

It was not a pleasant experience. Expensive lesson as the Mobil 1 oil was only $8 / L AUD.

Shell Helix 5w30 HX8 is my preferred or Shell Helix Ultra 5w-40.
