Will it be okay to use Regular Gasoline to a 20-year old engine? I got used to using Petron XCS but now it has E-10, and my carb is giving in. So I decided to use non-E10 gas which is the Regular Gas only.

will it harm the engine or will it be better?

i mean, the engine was made by the time there were there are no special gasolines like shell velocity, v-power, petron xcs and blaze

Most cars built from the mid 80's were designed to run on 10% alcohol.

With a carb, I would probably run straight gas, if you had FI, then run the 10%.
FI can compensate for the increased fuel requirements, better than a carb.

One thing you DO NOT want to run is methanol, it can cause harm to engine.
