Nice selection of Castrol Magnatec 10W30, 10W40 and 20W50. All API SP. That should cover most applications, from thin to thick.

Fuchs now own Nulon, so there will be a lot of product overlap. You can get a Nulon Apex+ Diesel 10W40 that is API CK4 and ACEA E8/E11. That meets your requirements.

Hey Mate, My local Repco has Castrol Magnatec SUV 5W30 C3 full synthetic at $110 for a big 7L jug. That’s full price. Wait for a sale and I’m sure you’ll get it cheaper. Just another option for you.

Mobil 1 15W50 No need to mix when this Mobil 1 Full Synthetic is available. It’s a high zinc oil, is that what you want? Do you have exhaust cats to look after?

At SCA for the next few days, 5L of Penrite Enviro+ GF-S 5W30 full synthetic is 45% off at $42 It’s API SQ and GF-7

Penrite Vantage 10W40 full synthetic A3/B4 is $61 for 6L at Repco. Down from $88.

Tomorrow is ANZAC day in Australia and New Zealand, so I'm listening to "And the band played Waltzing Matilda" by Eric Bogle. My favourite version is from the Irish band The Pogues.

When I joined Shell / Pennzoil PurePlus GTL (gas to liquid) was all the rage. High purity and low volatility. Some of the Pennzoil Platinum products listed very low Noack numbers on their product data sheets. Then formulas changed and Noack volatility was no longer listed by Pennzoil. Then...

I consider G-05 to be the modern coolant for anything older, and many things newer. It’s a hybrid coolant (HOAT) that contains organic acids (OAT) for long life, but not 2-EHA. But it also has some silicates like old-school IAT, but at a lower concentration so that it doesn’t cause any problems.

According to the data on the Shell website, the oil has a KV100 of 15 cSt and a TBN of 10.1 With zinc (ZDDP) at 1200 ppm, that makes it a strong oil. Shell says it meets API CK-4 and SN. Ref: https://www.shell-livedocs.com/data/published/en/5e129bc2-8941-43f1-81c8-0c6345b45e33.pdf

I always go for high HTHS and low Noack. Given the figures above, that says 5W40 or 10W40. Given that both offer sufficient cold weather starting, I then look for the lowest KV100 viscosity for the highest HTHS. This points to the lowest VII polymer load. Which is the 10W40 in this case...

I think the original Mobil 1 over here was 15W50, or at least the first one I recall being advertised.

That sounds like a good plan to me. If possible I like to crack fresh oil containers for an oil change.

It's a great oil, and you will be fine, old or new vehicle. When it comes to seal conditioners, API constricts you from above and below, so there is only so much wiggle room. It's a non issue.

Thank you for posting. They are great pictures.

Low SAPS (Sulphated Ash %) is to protect the exhaust emissions control systems. So yes, if they don’t exist, you can then run high SAPS Euro oil like A3/B4. It should have more TBN for longer oil life and higher ZDDP (zinc) for less engine wear.

Mobil 1 15W-50 with 1320ppm zinc.

Understood, thanks. The Valvoline Restore and Protect 5W-30 was definitely worth a try.

Any improvement? This is my first OCI with the Valvoline Restore and Protect 10W-40 in my GM Cruze 1.8L. So far, no improvement for me, but early days, I’m only ~ 2.5k miles into my first run of Valvoline Restore and Protect. Consumption is pretty standard at roughly a bit under a quart.

Same here, but we still run 10W-40 in them and keep our warranty. It’s in the constitution or something.
