Evap monitors-Do Diesel engines use them?

I am curious, do diesel engines use Evap Monitors like gasoline engines? If not why?








No, they don't need to. It has to do with what is called Reid Vapor Pressure"RVP". This is an established method for measuring a fuel's volatility( the tendency of a liquid to evaporate under a given set of conditions). According to the EPA the least volatile blend of gasoline has a RVP of 7.4 psi at 100 degrees F. Diesel fuel No. 2 has an RVP of .022 psi at 100 degrees F, making evap emmisions a non-issue in diesel powered vehicles.

More.. on ways of saving money at the gas pump!

There is this "thing" circulating out on the Internet about several different ways of saving gasoline. It has been discussed on our mailing list. We pretty much dismissed the ideas.



Listen to the clip below where Motorweek's Pat Goss puts these issues to rest as well, on his weekly radio show.

TPMS Can Track Your Car!

Tire Pressure Monitory Systems (TPMS) lets on-board vehicle computers measure air pressure in the tires.

Did you know that with minor limitations, TPMS can be used for the very purpose of tracking your vehicle in real time with no substantial investments!

Listen to the clip of Dr. Richard Shurtz, President of Stratford University, host of Tech Talk, a program about computers and information technology tell about how TPMS could be used for tracking your vehicle.

"Premium fuel recommended for best performance"

My owners manual says "Premium fuel recommended for best performance". I have heard that if I don't use premium grades of gasoline more deposits would form in the engine. Is this so?

No! regular gasoline actually has more energy in it and it burns more rapidly, so your apt to get a better burn with it, and end up with less deposits leftover. Premium fuel burns slower and there is also this myth that it contains more detergents cleaners which is not so. If your using a "Top TIER" gasoline then all grades of gasoline must be approved by the automakers as providing TOP TIER Detergent Gasoline.

The reason for the term "Premium fuel is recomended for best performance" has to do with tests run by the manufacture such as 0-60 MPH, which are performance claims.
