![]() ![]() ![]() Some of this may have to do with the fact that gasoline is more highly refined, whereas diesel is a heavier fuel and so is more prone to going "off-spec". There certainly are more diesel fuel additives out in the marketplace, both with multi-functional additives and the single function treatments that fuel suppliers have to use in order to make sure the diesel they're supplying performs the way it legally should. ![]() If you compare the ASTM specification sheet (the properties list) for gasoline and diesel, diesel seems to have more properties that need to be protected by additives. Not to mention that the diesel engines themselves are more efficient and are constantly being improved, such as with the new "common rail diesel engines" they're making.ĭiesel Fuel Needs Additives More Than Gasoline Does Because They Have More Properties Needing To Be Protected All diesel engines made now have things like particulate traps and filters that trap all the black smoke that used to be dumped out into the air. In the last 10-20 years, the government has required diesel engine makers to install special emissions control equipment that have really helped clean up the air by keeping diesel fuel pollutants from getting into the atmosphere. Granted, there may be some old smoking diesels that were made back before the new requirements, but those are becoming fewer and fewer as they die out. Like we just said, the image of the diesel engine belching black smoke is a thing of the past. Diesel Engines Are Cleaner Than They Used To Be But what isn't long gone is the great mileage you can get with a diesel car - 50 mpg or more. The image of the noisy diesel engine with smoke belching out the back is long, long gone. Diesel cars today perform just like their gas-powered counterparts and look just as nice. It is partly due to these standards that the old image of a diesel engine with black smoke belching out of the tailpipe of a big rig is a thing of the past. Some of it is an intentional switch of focus to hybrids. Part of it is the automakers not wanting to wrestle with the government's tougher emissions standards. In the last 3 years, car makers seem to be moving away from diesel cars - none of them have stopped making them. Diesel Cars May Not Be As Popular, But Are Cooler Than They Used To Be We like to call them "the things you never knew you didn't know". Mods feel free to move this thread.Here are 5 things you may not know about diesel fuel and the diesel fuel additives used to treat it. I will find out first hand what it does for me. I seem to be running about 600 miles a week so it wont take long to scope out. Have about 4k before the next oil change, should be enough to do its thing, if anything.įor those interested. Not bad and reasonable to evaluate at that cost. I will report feedback on each for those who are interested. Once that is installed and the next oil change comes around, I will do the injection cleaner, then the FR3 additive. I did a different oil cleaner some 30~40k miles back and saw no change IIRC, Blue tech? (posted in the newbies thread). Being that I'm on the Royal Purple oil now for about 200k miles, it will be interesting to me to see if this has any effect on engine performance. Did a lot of google searching on these and most of the feedback was positive. Came with the stiction remover free for a 16 oz bottle. Put in an order for the Hot Shots FR3 friction reducer and diesel extreme. ![]()
