Title says it all. Mine is an NB1 1.8L, meaning no VVT. OM states to use 10w-30 over 32 F, and 5w-30 under 40 F. I'm thinking that 0w-30 will be just fine? The car will only be driven in warm weather and garaged and stored during the winter. Engine has been well maintained and it runs like a top with 122,000 miles on the clock.
