Parts of Canada can get awfully cold in the winter...

Oops! LMAO!

Chris

but shirley the 5w end is good in very cold weather ????

Yes, certainly. 5W is less viscous in cold weather than 10W. The W
stands for Winter BTW. A 5W-30 oil stays more fluid at low
temperatures than a 10W-40 oil, but the latter retains viscosity
better at high temperatures than the former. Good low-temperature
performance is important for starting in ice-cold winter weather if
the car's been outside overnight, and for the first mile or so
thereafter while the engine warms up. Retaining viscosity at high
temperatures would be important if you were planning to drive across
the Sahara in summer, for example.

I can't really see that you'd be troubled by using the 10W-40, unless
Glasgow is hit by an extraordinarily cold winter in 8 months time.

And don't call me Shirley

OK Chris.......wondered what the W stood for ... I will only be using the
convertible April to September so fine I was just really worried about seals
swelling ..... etc
