10 psi
It should have a minimum of 70 psi.
Compression testing is done on engines and it establishes whether the engine has good compression. Good compression is needed for the engine to start easily and run efficiently.
480 psi minimum
When a Hyundai is losing compression in its engine the car will not run properly. Symptoms of low compression are misfires, stalls, and overheating.
It can ..but the compression ratio require 91 octane minimum...
Minimum is 9,7bar.after that will run poor on low rpm.
Have a compression test run on the engine.
Air flow in to and out of the engine, adequate compression, fuel and ignition.
The engine needs fuel, compression and spark to run, it is missing one of those.
The engine needs fuel, compression and spark to run. You are missing one of those.
Low compression will not cause an engine to not run. It may not run efficiently but it will run. Low compression on all cylinders is caused by wear, and can only be fixed by overhauling the engine. Low compression on just one cylinder can be a blown head gasket, burnt valve, or a broken ring on that cylinder. I also depends on what you mean by "below average". An engine with lots of miles may very well have a compression reading that is below the factory specifications and not be cause for alarm. It depends on how much below specs that compression is. In any case, the only fix is to open the engine up.
So the engine can run on regular 87 octane gasoline.
