Does high test gas make a difference?
If your car doesn’t require premium, fill up with regular. In a consumer notice, the Federal Trade Commission, notes: “In most cases, using a higher-octane gasoline than your owner’s manual recommends offers absolutely no benefit. It won’t make your car perform better, go faster, get better mileage or run cleaner.”
Does higher octane advance timing?
So increase octane allows the earlier timing due to that resistance to pre-ignition. Simple, higher octane burns slower but more complete. Since it burns slower you have start the ignition sooner, hence advancing the timing.
Will high test gas hurt my car?
The higher octane gives premium gas greater resistance to early fuel ignition, which can result in potential damage, sometimes accompanied by audible engine knocking or pinging. If you use premium fuel because your engine knocks on regular, you are treating the symptom, not the cause.
When to do a bump test on a gas detector?
A bump test, also known as a functional test, should be performed at the start of each day’s use. This procedure tests the alarms and sensors of a gas detector to be sure they are functional. The test exposes the detector to a known concentration of gases that exceed the lowest alarm set-point for each sensor.
What do you need to know about bump testing?
The aim of the bump test is to make sure a gas monitor is working at its optimum by briefly exposing the unit to a known concentration of the target gas. The reading is compared to the actual quantity of gas present, as stated on the test gas cylinder, and if the detector goes into alarm within an acceptable…
Is the bump test gas the same as the calibration gas?
The calibration gas and bump test gas are often the same, so when buying your bump test gas, don’t worry too much about whether it’s labeled a bump gas or a calibration gas. It’s better to look instead for the proper concentration of gases, your preferred canister size, and delivery method (flow valve or manual trigger).
What does a bump test on an alarm mean?
The only way to verify proper sensor and alarm operation is to perform a bump test. Bump testing is the process of briefly exposing the installed sensors to an expected concentration of calibration gas that is greater than the low alarm set point.
What does it mean to bump test a gas detector?
Bump testing is a procedure to check a detector reads to the expected tolerance and initiates the correct alarm signals. Bump testing does not involve any calibration activity and can be easily undertaken with minimal training (see video below).
The aim of the bump test is to make sure a gas monitor is working at its optimum by briefly exposing the unit to a known concentration of the target gas.

What’s the difference between bump testing and calibration?
One of the many questions we get asked here at IGD, is the difference between bump testing and calibration. Bump testing is a procedure to check a detector reads to the expected tolerance and initiates the correct alarm signals.
When to put premium gas in your car?
That said, if your vehicle requires premium fuel, it’s a good idea to top it off with the good stuff as soon as you’re able. If you’re really worried about the engine developing a knock, you can add just enough regular fuel to get you to the next station, but be sure you have enough fuel to reach the destination.
