The only additives I'd ever use is a complete fuel system cleaner - nothing else at all. I have had poor quality fuel at times pumped into my car and I have seen a drop in performance and mpg. I know from my own experiences that not all fuels are the same. There is certainly a difference in octane and maybe some differences in the additive package. The company that produces the fuel may have standards to set and observe. But nothing stops the fuel retail outlet from tampering and sometimes even altering the percentage of ethanol or sometimes cases of kerosene in gasoline are not uncommon in some places. Even the best gasoline in the USA may or may not match the average quality of gasoline available in Germany, France or Britain. VW and Mercedes had issues with their fuel injectors getting gummed up or clogged and had to modify the designs to be more robust for use in the US. That may be why similar sized cars sold in the US and in Europe get varying mpg (also because of the difference in measuring units!) but also because of sulphur content and other factors. You can get away with no additives at all for the life of your car. But that largely depends on the design of the components and how much torture they have been through during their life cycle. If you happen to keep filling gas fortunately at a reliable location -then you probably wouldn't need additives ever to keep the engine clean. But how would you know this? - No one knows for sure. So to stack the odds in my cars favor, I'd rather add a fuel system cleaner which is NOT a snake oil but a necessity in some locations (very different from engine oil or coolant, transmission or gear box additives - these are not recommended by manufacturers) If fuel system cleaners were optional and all fuels were equal - then all used cars would have immaculate injectors/systems. Until that is proven to be the case, I'll stick to my theory.

Replying to: steve_ (Nov 25, 2008 2:44 pm) I think most people should just gas and go. Most cars have fuel filters that should take care of any gunk in the tank, and I'm not inclined to fill up twice as often. The only damage from running the tank dry is that the fuel pump is lubricated and cooled by the fuel. If there is no fuel and it is sucking in air, it is neither lubricated nor cooled. So, now you have a tankful of fuel vapor and hot fuel pump. I guess there is a reason why Honda set those low fuel lights at about a gallon reserve so that no one goes KA-BOOM! I use Chevron with Techron fuel additive before each oil change. I usually fill up at whatever station has the lowest price. All the fuel here in Buffalo comes out of one refinery in Erie, PA. So, it does not matter who you get it from.

Replying to: blueiedgod (Nov 26, 2008 12:51 pm) That's pretty common, but the distributor is supposed to add additive packs for the various tanker loads. So the tanker going to the local Chevron would have some Techron added. Or so I've heard. |

Replying to: d07 (Nov 17, 2008 10:42 am)  60mph. 2 major issues/concerns: 1. Due to getting discounts from grocery store gas stations, I tend to run my tank empty. Owner's manual says 2.3 gal left after fuel needed light comes on. That typically happens 25 mile to empty on my CRV. Then I will put ~ 13.5 gal before pump shuts off. I can put another 4 gallons if I throttle gas nozzle, which puts me over 17 gal in tank. Manual say tank capacity is 15.5. Have others experienced this is my CRV unique. 2. Just took in for 2nd oil change. Maint code was B16. They (Honda Service) said rear differntial fluid needed changed + many other inspections required. Total cost was over $180 with OLF + tire rotation. Did I get ripped off? This is the 1st AWD vehicle that I have owned. Is this par for the course or is has Honda set up something to the the dealers service $?.

At 18,000 miles on 08 CRV EX-L, I too got maintenance minder saying B,1,6. Is it really neccesary to change rear diff fluid already? Car is running great with no sounds from rear, thinking of waiting until 30,000 miles.

Replying to: kevman3 (Dec 04, 2008 7:45 am) Waiting until you hear noises is a bad idea. The goal is to keep everything moving smoothly, so there are no noises. Would you wait until the engine starts knocking to change the oil?  Kip |
