Thank you! Yes, 2023 Fiesta ST. Original colour (Mean Green). One of the final shipments ever to Australia from Cologne, Germany. Epic car.

Totally agree with that. The post I quoted said the journal bearing constantly reverses, and that didn’t sound right to me.

Penrite also has a few 70s: 40-70 https://penriteoil.com.au/products/hpr-50-40-70-mineral 30-70 https://penriteoil.com.au/products/stops-oil-burning-30-70 25W-70 https://penriteoil.com.au/products/hpr-40-25w-70-mineral

The 0W-8 cars can run up to 10W-30 in Australia.

However, there are several C3 oils which meet the fuel economy requirements of C2. These are ‘dual-rated’ C2/C3 oils. They have the 3.5+ HTHS requirement for C3 but demonstrate the fuel economy requirements of C2.

So stop using the 0W-20 then.

Most likely the case. It won’t be a semi-syn as we think of a semi-syn.

You can buy it straight from the source https://shoplubricants.vivaenergy.com.au/shop/products/passenger-car-engine-oils/shell-helix-ultra-5w40-sp-5l-910281819 Or from Repco...

I would run either something like ESP 5W-30 or Valvoline Restore and Protect 5W-30. You don’t want a xW-20 in an engine with historical timing chain issues in such a big heavy car.

Try Valvoline Restore and Protect 5W-30. It should stop the burning.

Correct. I was more saying it is possible to burn fuel once it’s outside the combustion chamber.

With direct injection, you can also inject fuel during the exhaust stroke. That’s how diesels perform DPF regeneration (except those with a dedicated injector in the exhaust stream).

The reason the ignition timing is retarded during AWS is so some fuel is burned in the exhaust past the exhaust valves. But the mixture is not enriched like an old school choke – you can’t do that and meet emissions these days.

They don’t run rich during that cold start cycle – they retard the ignition timing significantly and open the throttle wide to heat up the cat as quickly as possible. Because the NA Skyactiv engines use really long 4-2-1 headers, it would otherwise take way too long to heat the cat and the...
