Oil Change 40W40?

I have a 1996 196 and PCM recomends using 40w40 the autoparts store does not carry it. I think we always used a common oil like 10w30 in my parents 88. Does everybody use 40w40 and where do you find it?

I use Castrol 40W in my 2000SN. Pep boys or Kragen both carry it.

my thought is... any oil is better than no oil.

I had the same problem, 40W hard to find.

I used straight 30W when I changed the oil prior to winter storage. Does anyone see this as being an issue? I'd hate to have to drain it and re-fill with 40W prior to running it for the season is someone can't convince me otherwise.

tnp,

I believe CC actually recommends 30W when the temp is below 50 Fahrenheit. I'm pretty sure I've read this somewhere, now whether that 50 is air or water temp I don't know... I have 30W in mine now from last winter. I've only taken it out twice this year, the water is real cold (40-45?). the temp gauge didn't get over 150 the last time I took it out, putting around most of the time, and a little WOT, stayed between 140-150. To me it seems like the 30W would be fine if not prefered in this situation. I will be changing over to 40w probably next time i take it out. I think it may start to warm up around here soon.

Thanks guys.

When I went looking for oil the auto parts (stocker) said the closest they have to 40w40 would be 10w40 which he said its not really even close. So I went back and got 40w.
