  • diesel vs gas

    thinking about switching my rig over to gas,truck and welder. i currently own a pro 300 cat. I am interested about the trailblazer 325, does anyone know if the new ones coming off the production line have all the bugs worked out yet?

    diesel over to gas

    Hey G.blackbeard what is it exactly your wanting to achieve by switching over? That pro 300 really gets amazing fuel economy, and there really isn't a better machine in its class. Many of the old pipeliners have switched over to these out here in the patch.

      i am tired of the maintenance costs associated with diesels. i want a new truck, but cant swallow the $10,000 more for the diesel motor/tranny, then spend up to 10 cents/litre more for diesel fuel. Does not seem to make much sense. I was thinking about the 325 simply so both units run the same type of fuel.

        10c/gal more is cheaper than the gas mileage difference to an equivalent class gas rig. Even more so the larger truck, or toting around heavy loads.

          The gas verse diesel debate will never end, but do the math and diesel is not cheaper. First take a f450 chassis, v10 vs diesel. V10 will get 10 to 12 on the highway, 8 to 9 in the city. Diesel will do 8 to 10 in the city and 12 to 14 on the highway. Now keep in mind if the truck idles at all regen will kill a diesel in fuel economy. Also the diesel maintance costs are much higher, ie 200 doller oil changes, 50 to 100 doller fuel filters, and if anything fails on the diesel expect to pay huge bills. In my mind a new diesel should be sold right before the 100k mark or when warranty ends. Fixing these new diesels is brutally expensive. Now take a v10 simple, only thing which fails on them are coils, exhaust manifold studs, and an oil change is $40.

            i just did injectors in my 6.0l and it was around $4,000. that is just shy of half the price of the diesel option on a new truck. What r 8 new sparkplugs worth?lots of guys i know buy new diesels then spend up to $2000 just so they run properly and get more than 10mpg.

                If you can,t fix your own truck then yes,they are expensive.I can fix 99% of my own repairs myself but i was raised in a auto shop dad was a mechanic owned his own shop 35yrs.Was a tranny rebuilder,so i was born to turn wrenches.No dad can,t weld and i cant rebuild transmissions.

                    Just about everything you just stated I have had exact opposite experiences. That's just me though, and I am not toting around a fully loaded service rig. My mason who is hauling pallets of block constantly just told me he is saving over $500 a month in gas over his old gas 450 with his new 550's which are diesels. Never heard of a large gas rig getting better than 10mpg under any condition other than coasting down a hill.

                      Don,t use synthetic oil.Got 202k on my 7.3 with conventional oil.In mass where you buy your oil must take the old stuff back free of charge.Must b different up there.

                        gas vs. diesel

                        I suppose the issue here isn't necessarily gas vs. diesel but rather diesel vs. diesel if your in the line of work that travels considerably as I do. I've put every bit of the 215,00 on this 5.9 and besides the maintenance and proper care only had to put fuel and new tires roughly every 50k. 24 MPG ain't no joke when your running cross-country. Also love that cat purring on this pro300 when I'm behind my pancake. No doubt about it if your travel'n 15 minutes from the house that gas vs. diesel is a no brainer...go gas.

                          First i said new diesel ie 6.7 ford, 6.7 cummins, or duramax. You can not compare the cost of a 7.3 or 6.0 to the new common rail engines. First the oil is 18 dollers a gallon, depend on the engine but they take 4 to 5 gallons, the filters are 25 to 60 again depending on the engine, also you are a fool if you dont change the fuel filter every oil change, also you should be oil sampling the oil. Also i was quoting what the dealer would charge, i work on these trucks for a living, i will not do any service work on the engine until the warranty expires. Simply put when warranty comes up my customers and i do not want a rejection based on maintance.
                          As for people saying well when it breaks i can fix it...good luck. First the parts are beyond expensive, is someone going to replace 4 injectors at 450 a pop? Can you pull the cab off to do headgaskets? How many poeple have the scan tools to troubleshoot? Also for all the tuners out there pulling the emisssion crap of the diesels, how long before the diesels will be subject to the same emission tests that cars have to do.
                          Im not knocking the diesel, i have 2 both 7.3's. I do beleive when all the costs are added up, intial cost, maintance cost, fuel economy it is very difficult to come ahead with diesel. In the past it was no comparison, until you been hit with the repair bill on a new diesel, or worse the downtime, its hard to beleive that gas might be a bettar choice. Also just to really annoy some out there, wait until the natural gas option really kicks in. Currently i have a customer who has converted 3 of his rigs to dual fuel, he is filling up at .90 cents a gallon, and getting within 90 percent of gasoline. Nice thing about his systems, isnhe filps a switch and he runs off gas.

                            I hate the stench of diesel, one drop on you boots and you smell it for a week. Around here the diesel pumps have so much fuel on the ground it's hard to avoid getting it on your boots. Because of the stink I dread filling up my 5 gallon cans for my small 855 JD tractor. The fuel truck used to come by and fill my 55 gallon drum set up on a A-frame for me but now the driver says 55 gal isn't worth his trouble.

                            The starter went out in my buddies semi and it cost him over $2000 to get it rebuilt.

                            They both have there place, I just hope I'm one that never is put in a position where I have to buy a diesel.

                            Then you have welders that will work all day for a box of fishing worms and six pack and be happy and content as flies on a fresh cow pie.

                              t.b325

                              Back to the original question, I am seeing more and more of the new 325's and all the welders I've talked to are very happy with their performance not to mention the fuel savings with the injection. As best that I understand it they are not based on the traditional solid state phase control technology but rather the inverter like pipe pro(based soley on inductance control) . As far as any bugs with it only time will tell. Another welder in our group had a board go out in his sa200 and bought a t.b.325 last Thursday, I'll keep you posted.
