I'd have to agree with this also. Personally, I don't go for the gimmick
stuff (Slick50, etc.) but a couple years ago I tried the Castrol Syntech
on my '88 Corolla. I noticed an immediate improvement (the engine seemed
to come alive.) Although it does tell you to be careful with older cars
(I ended up having to replace a valve cover gasket because the synthetic
stuff just seaped right past the gasket that was in place) I don't have any
complaints.
If you remember their add on TV (its the one where they have a roomful of
engines runing without oil, the only one that didn't seize up was the one
running Syntec) I can offer a real life story to that.
I checked my oil about 2-3 months after putting the syntech in. When I
looked at the dipstick, there was absolutely no oil on it. Even with
close to no oil in my engine, I never heard a valve ping, or experienced
any problems. I just added a couple quarts of oil and went on my way.
(Dak Content) I'm considering putting the syntec in my Dak whenever I
receive it (hopefully this week sometime, it rolled off the assembly line
last Wed.) Can anyone offer any reasons I shouldn't put this in my
engine? (318, 5speed..)
