I just couldn't resist. I stopped in a
Petro Canada truck outlet. They had the
Duron 5w40 for $5.36 CDN/litre. I bought
a case of 12 to use in my BMW before winter
storage. I'll keep it in until next summer.
I was thinking of putting a 40 wt oil in
my car for sometime now. I cannot find
Mobil 1 0w40. Delvac 5w40 and Castrol 5w40
costs $ 8.50 approx. per litre. Plus, I read
on this forum that Castrol Syntec 5w40 is a
GRP.III anyway so why spend the extra money?
The specs for this oil are as follows:
FLASH POINT: 233 C
VIS. cSt @ 40C: 95.5
VIS. cSt @ 100C: 15.5
VIS. INDEX: 173
HT/HS @ 150C: 4.2
POUR POINT: -45C
TBN: 10.9
