Subject: Re: 5W50 synthetic oil grade

He is saying that 50 grade oil is TOO heavy for a turbo charged engine. Not that difficult is it? He is correct. Any 50 grade oil is too heavy for even an OHC engine, let alone a turbo. One needs the thin(ner) oil to lubricate quickly from cold, and also when hot. 50 grade might be appropriate for an old pushrod engine but not today. I guess the ideal oil for a Saab would rate something like a 0W-40 synthetic. Anyone who says you can't use a synthetic in a Saab engine is lying. Saab actually market their own Turbo spec oil. Funny old thing, its a synthetic. Go figure. -- Spammers, here's some for you: ucenopsamgov Justin VanAbrahams wrote in message <>... >Ken Washington wrote: >> >> Riff, >> >> The W50 of the multiviscosity is not needed.
