Fully synthetic 5W40 or 10W40 according to the book. I prefer 5W40.
5W40 covers the widest temperature range of the specified oils, it has been down to -17C here, lower with wind chill. At the other extreme it was close to 42C this year. 5W40 makes cranking in extreme cold a tad easier.Do you visit Alaska with it often?
That's a bit higher mileage than the 167K on my project car which also runs on 5W40Good point, I do think with the extra mileage on mine at 210,000 I like to stay with the 10w40. I did used to use the 5w40 in my old omega 2.0i as it made a massive difference to it in many aspects but it had far less mileage.
40W is not thick?If it’s old engine bit thicker would be good, if your in warm climate also. Over 30c here this year and although no problems I think thicker oil would have helped in the warmer weeks, but no point for few weeks of the year that it mostly spent being stripped.
One thing I’ve only now noticed - heat wave has popped the black vents in my dash, don’t think they’ll ever sit right again
No problem with mine on a 500Km round trip in 41C
(Poitiers to Noirmoutier plus a bit of running around)
