Southwest Airlines "Silver One" Airplane ModelSouthwest Airlines 737 airplane model. Boeing announced it was developing the 737 300 in March 1981. This new variant started off as a simple stretch over the 737 200 but Boeing decided to adopt the CFM International CFM56 high bypass turbofan (jointly developed by General Electric and SNECMA) to reduce fuel consumption and comply with the then proposed International Civil Aviation Organization Stage 3 noise limits. The 737 300 flew for the first time

Quieter and more mpg in TDI
Size: 1 Count (Pack of 1)
Didn't really believe the hype. Did a little research and watched Project Farm and decided to try. Im not a snake oil guy....but I will say my 2013 common rail TDI is quieter and I get a tad more fuel mileage. Does it pay for itself? Well, it does get better mpg, but I feel the reduction in noise most likely relates to less wear and tear and thats good enough for me. Im only using 1oz per fill up (about 14 gallons) so it lasts a very long time. I get 40mpg and im not light footed.
