Just in the process of buying the new kia..

Oil has changed 2021 onwards for the 1.0 Kappa tgdi from ACEA C2/c3 0w 30 to API. SN 0w20.

Wonder which one the car gets being serviced as they have bulk oil..

Lee Power, i think it id slightly poor form to be dissing the engine on another members car, when they are not actually reporting an issue. John: I thought all cars had these different temperature ranges? On the discovery 2 v8 owners manual it gives two options, which I ignore and use 20/50: 10W/30 will protect from -10oC to +30oC 10W/40 will protect from -10oC to +50oC. For the td5 they say 5w30, 40 or 50 if I recall correctly. I would also factor in your style of driving, is it lots of short trips or long runs?

I've owned my Purecrap 130 powered 308 since May 2018, its had to have the inlet valves decoked at just 34k miles due to a known design flaw ( which Peugeot UK where reluctant but eventually paid for )

It's also been recalled for the JZR timing belt check due to another known design flaw.

A mechanic friend of mine had to replace the timing belt on his wife's 2017 Purecrap 110 powered 208 as it was starting to break up but pasted the JZR recall check - he found out Peugeot are now on generation 4 timing belts which is the kit he fitted to it ( 4th time lucky, maybe, who knows? )

A work colleague had to pay to have a replacement timing belt & the oil strainer cleaned on his 2017 Purecrap 130 powered 308 as it was built after the JZR recall cut off point with a generation 3 belt but it still failed at 42k miles with a full Peugeot main dealer service history & Peugeot wasn't interested in an out of warranty goodwill claim.

Go have a look on the various Peugeot / Citroen forums & see the amount of unhappy owners that have had failures / little to no help from Peugeot / Citroen.

These engines in my opinion are total garbage because of known design flaws that have now showing up & ill never buy another Stellantis product ever again.

10W/30 will protect from -10oC to +30oC 10W/40 will protect from -10oC to +50oC.

I have never really understood how a few degrees change in ambient air temperature from a hot summer day (30deg) to an exceptional heatwave (40deg) would affect the oil temperature (110 - 125) in a 90 - 105deg pressurised water cooled engine).

For a Purecrap engine in the UK Its not about viscosity, its all about the oil being approved to PSA B71 2312 spec.

Fine. Perhaps I didn't make my earlier point clear - Pug usually advises more than one viscosity grade for each engine. Maybe different grades meet the B71 2312 spec ?

Most if not all PSA B71 2312 spec oil I've seen are 0w30.

As I've repeatedly said, the viscosity isn't important any more, the vehicles manufactures oil specification for the engine concerned is what's important.
