Just looking what is now available on pds, it is inferior oil. Bit better than before, but still..I was searching for answers the other day and came across this thread., it convinced me.
Castrol 5w40 vs Castrol 0w40
I see a lot of people praising Castrol's 0w40 on here but I never see anyone talking about their 5w40 at all, is it really that inferior? My local Costco carries the 5L jug of 5w40 for $32 CDN, although it's still cheaper for me to buy Castrol 0w40 across the border in a US Walmart. So what is...bobistheoilguy.com
Valvoline 5W40 European Vehicle also available in Wal Mart is better.
