I understand the relationship between higher compression and better FE, got it...

But unless you are experiencing drivability issues, I wouldn't bee too concerned on whether or not the compression #s come on the lower end of the allowed range or not. (if #s are way out of range you should be experiencing drivability issues).

Yes, by all means take compression measurements for your own awareness. After all, compression #s are a good indicator of the overall health of an engine. So yes, be aware of your engine's health.

But there is no "quick-fix" for a REAL low compression issue. And additives can only temporarily mask a minor problem... If the engine runs good, then I wouldn't waste my time chasing imaginary FE improvements that may or may not be gained from a temporary few PSI of cylinder TEST pressure increase.

Obviously this is just my personal opinion and I'm sure someone may differ.
