Do a leak-down and compression tests, if they are good, give it a shot, and if you burn it, oh well.

Its never to late, that is an urban myth.

The whole thing started in the latter days of hot rodding (70's - 80's) Older cars built back then had fabric (main seals) and cork (VC gaskets)
When they got older and had tons of miles on them , addition of synthetic oil would cause the seals to leak , because it would clean out the grime build up and change the tolerance , creating a leak. Most newer cars built since 89 - 90 use neoprene seals , which also contains an internal spring. These type of seals rarely leak , unless exposed to uneven pressure , were installed improperly to begin with , or were exposed to extreme temperatures which would warp the seal housing.
I personally used synthetic oil in my 91 Beretta GT , which had 168K miles on it when I got it , and it never leaked a drop. I'd say if your SOHC 1.8 is in good shape , go for it.:bigthumb:

i switch to synthetic oil in my 95 civic at 100k and never had even the slightest hint of a leaking problem. RockinWRX is right there souldn't be a problem with leaking if it isn't already one

the easiest way for me to put would be that it lasts a lot longer, a whole lot longer than regular oil, since was originally made for jet engines

Just ignore them. Trolls can't stand to be ignored. :wink:

if i were you i would go for it. the worst thing that is going to happen is your going to burn it. i would run compression checks just so you dont waste your money on synthetic if the car is burning oil. because synthetics can be slightly more expensive or about the same in the longrun. depending on manufacturer(of oil) and personal beliefs. i got my car at 82,000 the guy before me was running a synthetic blend. when i got it i switched to a fully synthetic(preference Amsoil) and it has never had a problem.
