Boy howdy to ya,
To my knowledge (I'm ignorant on this really) the fuel hasn't changed
octane wise, additives are a different story. But anecdotally I've ran
87 without a problem in my 1.9l '85. I try to run 93 octane when
possible but these days you'd have to sell a kidney to afford it! Octane
ratings in Europe may have been different, and they certainly had
different choices (ever seen 91 oktane in the USA?). While I never had a
problem with 87 in the van, my 16v Jetta could really tell what I gave
it, but that was a sensitive engine to say the least.

My point finally... octane ratings matter but I never had a problem on
my 1.9l, but YMMV... so why not run it and see.... you won't do any
damage with a tank of the cheap stuff.

There's my 2 cents... and yeah I'm still alive first post probably all
year yeehaw! :-)
