GTV4EVR,

Thanks for setting the record straight. But would you please take another look at your '69 owner's manual? The reason I ask is that I have a copy on CD which appears to be for the injected 1750 U.S.-spec series (Berlina, GTV and Spider) cars for 1969, but it doesn't have the date on it. The folks who made the disc (CarDisc International, Ltd., 2004) claim the manual is for 1969, and it does contain a boat-tailed rather than a Kamm-tailed spider. So my assumption was it's for a '69. Anyway, page 57 provides the oil specification, and it is for 20W-40, NOT 20W-50.

The CD also contains an owner's manual for a '69 Euro-spec 1750 Berlina, and on page 31 it specifies a 20W-40 weight oil.

The CD has also a 1971 owner's manual which matches my original.

So we have a little bit of a mystery, which does not alter my point that you can use a variety of modern oils in these old cars, depending on your druthers. I'd term the use of a 20W-50 as "old school" in most cases, but as I'm fast approaching 60 years old, that label is not meant to be offensive. Best wishes. . . .
