I'm in MA, and I use Castrol GTX 20W50. The brand is less important to me than the weight. In an older engine I like having the heavier oil. Since I do most of my driving during the warm months, I don't need the thinner side of a multi viscosity oil.
I would personally not use 10w-40 in any car. a 10w-40 uses too many viscosity index improvers to attain the spread between the weights. A 20w-50, while having the same "30" spread doesn't need as many. It still gets hot in Maine in the summer. I'd do the same that I do here in NY. 20w-50 (I use GTX) in the hot season and Chevron Delo 400 15-40 otherwise and before winter storage.
There has been considerable chatter on the 'net about many 'modern' oils having reduced additives that our older engines supposedly need. IIRC, zinc is one of the additives that has been reduced in the modern "Energy Conserving" oils. These tend to be the lower weight oils spec'd by current auto manufacturers - esp the 5W-20, 5W-30 and probably the 10W-30 and maybe the 10W-40 oils. Look for a 'starburst' symbol on the container with 'Energy Conserving" or something similar printed there. Avoid those oils!
Another option are 'diesel' engine oils. They are usually a 15W-40 oil and are touted as good for our older engines. I use Shell Rotella synthetic (5w-40) in my motorcycle (Honda ST1100) as the additives are also needed for its integral gearbox and wet clutch.
After you've made up your mind on the weight of oil to use, make sure you get the right tools. You'll need a 27mm socket and a LARGE capacity catch pan! I was amazed how fast that old oil poured out of that 27mm drain hole, and of course my drain pan held about 6.5 of the 7 quarts that came out! Other than that it was a pretty straight forward oil change, except for the extra 3 quarts I had to add, as compared to the old VW's I'm used to working on.......Good luck!
Oh, be prepared for almost none of the 'low profile' drain pans to fit under there. (hint: try the pan first before breaking loose the plug only to find out you can't catch the volumous cascade of ish)
I'm using it in my '79. So far so good. Watch out for leaks though. It doesn't clot like dino juice. I ended up replacing most of my seals last year before I found that out. Heck some of them were probably 26 years old.
Everyone I know who has switched to a synthetic after more than 35K miles has had the pleasure of watching it oooze from every engine pore. I wouldn't do it.
I remember back in 1976 coming across a guy in Kent Ohio with an absolutely pristine Fiat spider. Asked him what oil he used and he said GTX 20-50. I used it in my Fait and now I use it in my Alfa. If it ain't broke don't mess with it. BTW the Fiat was not burning oil at 145K when I sold it. That convinved me.
The right front stainless steel bumper on my 1966 Duetto had half a dozen various size dents or dings on the leading edge. The car either came to me with a dinged bumper 35 years ago or I've hit some large bugs. It really was not bad enough to warrant replacement of the bumper but it wasn't as...
I thought I would post a pic of the proper suspension stance for the Spider. The US models were "tampered" with to meet DOT bumper height (see pic of the Spider on the Home page..) and it seriously affects the handling of our cars. I had no idea until I installed the Alfaholics Fast Road rebuild...
I have an 86 spider and the last few times I went to start it, it wouldn't start until gave it a little gas.
Started it this morning and had to give it gas. But after it started the fuel hose burst right where it connects to the fuel pump. I got a bucket under the car and it drained out the...
I have an '86 Quad that I am looking to update the seats. The replacement leather upholstery kit for my year Quad is $1295 from Centerline. There doesn't appear to be a vinyl option in grey.
Replacement seat foam is $498 for the complete set (upper & lower - both seats) or $106ea for just...
We purchased our 1967 Spider from Rambo Motors in Portland Oregon in early February 1970. Since then it had seen 3 paint changes,
4 convertible tops, numerous tire and wheel combinations. Started out as a daily driver/work car, so it was used in all weather conditions
including snow. I even...
