Discount oil in Oz.

Autobarn sale from 9th November to 26th November:

Castrol GTX Ultraclean 15W40 5L For $14.99
That is a great price for 5 litres of semi-synthetic oil that is rated ACEA A3/B3, API SN/CF.
$3 per L is about as good as it gets in Australia. The regular price would be something like $40 to $45 for a 5L jug.

I’ve run the GTX UltraClean 15W40 in my Holden Astra before, it did fine for my standard 10,000km / 6,000 mile OCI, with two more jugs of GTX-UC already lined up to go. So no need for me to buy anymore right now.

BTW if you grab a few jugs of GTX-UC at this sale for $15 and a few Cooper oil filters at the previous AB sale for $5 each, that gives you a $20 oil change. Not Bad.
 
Bunnings (Australia on 19 Nov 2020) on-line is showing jugs of Valvoline SynPower 5W40 and 5W30 full synthetic for $33 each. That’s very good and this appears to be a regular price, not a sale price.

  • SAE 5W-40, API SN/CF, ACEA A3/B3, ACEA B4, MB 229.3, GM-LL-B-025, VW 502.00, VW 505.00, RENAULT RN710, RN700

  • SAE 5W-30, API SN PLUS, API SN, Resource Conserving, ILSAC GF-5, Ford WSS-M2C946-B1, GM dexos1™ GEN 2 APPROVED (Lic No. D10195GL103)
They also have 5L of ZEREX DEX-COOL for $24 and ZEREX G0-5 for $25

Indeed, I couldn't help myself and took a couple jugs home :D

Thoughts on this Castrol SR5? It's 0W40 Diesel and seems to be ACEA C3. For $20 during the black Friday sales at autobarn.

Also on sale at Repco is Edge 5W30 at $65 for 10L

Yeah I’ve seen that Castrol Edge 0W40 Diesel at Repco before at a super low price and thought about picking some up. It’s API SN/CF, ACEA C3 and BMW LL-04. But I can’t find it on the Castrol Australia web site, so maybe it’s discontinued stock.

It’s a full synthetic mid-SAPS oil. I was thinking of getting some and then blending it with some high-SAPS A3/B3 (or B4) mineral oil to make a 50:50 semi-synthetic.

But then I gave myself a good slapping and walked away. I have too much oil at home already.

I think Castrol have replaced it with Edge 5W-30 LL, which is SN/CF, C3, MB 229.51, Porsche C30 and VW 504/507.

They are both SN rated, so fine to use on their own anyway. Looking at a few spec sheets the 5W30 MB 229.51 has a SA of 0.75 and a PP -39 C of while the 0W40 BMW LL-04 one has a SA of 0.8 and a PP of -51C. That low PP says high PAO content to me.

Mixing the Edge 0W40 C3 with the GTX-UC 15W40 A3/B3 at a 50:50 ratio will give you 10L of 40 grade semi-synthetic for $35. If you were so inclined.

Geez I’ve almost talked myself back into it.

Not my style of oil, I would prefer a 15W40 or 20W50 mineral any day of the week. But if you like GTX 15W50, then the above deal is a very good price.
