O/P it's not confusing just pick what quality oil you want to use and pay for. Your (types) choices are simple: full synth or part synth. Your (coldness) number in the UK is simple : 5W/30 full synth will protect you from -30°C to +30°C. We've just had a period of 30°C+ in the UK. Am I bothered ?. No not even a little bit, it was not that temp up here in 'flat cap' land and I've used and trusted full synth with all four of my common rail CRD's for 40+ years without any issues - you get what you pay for. NOTE: I've posted the full Chrysler own spec issue engineers workshop manuals dozens of times on this site. I'm assuming what you claimed to be your Chrysler workshop manual was in fact a 'Haynes' generic book. Please correct me if I'm wrong. Best of luck.

Oil filler cap on my 3.3 petrol says 5w20!!!!!!! I do have the handbook and it can be almost anything in this country with our temperatures. So I use 5w30 because I can buy that anywhere, I've used my local autofactors standard stock fully synthetic stuff, Granville oils last 2 times at around 3000 to 4000 miles, as it has been doing way too many - way too short journeys with my Mrs, to her mums and hospital appointments. It had also been using a bit more too recently, which I am GUESSING is down to the clearances being larger in the engine when it's cold.

Ah now am I right that this version was built in Europe, like mine, so that would be why they've listed the Euro standard after their preferred API one?! Got to comply for the world's markets hey!! Either way, I agree, for these, fully synthetic, change it often enough, not on mileage as QinteQ says, keep it sweet! Oil is less mither, & cheaper, than repairs, probably anyway! Condensation forms in engine and exhaust on cold start up that is only evaporated off if it gets hot enough. That's then water in the oil if not - tiny amount each time though.
