What type of oil?
What type of oil is used in the 2004 Dodge viper? The manual says 10w30 and the cap says 0w40 called the dealership they said they would put 10w30 but then I bear 0w40 is what's recommended by viper engineers my... So I go with the 10w 30 and now I have really noisy lifters would I harm anything by going with 0w40?
