Sold my Honda Fit GD1 to a friend, the odo meter is now 73K, i got it at 53K and used it for precisely two years. I first ensured the CVT oil was changed more frequently to avoid any gearbox issues, and then once i found the additive i resorted to a normal 15-20K cycle. However i did not finish that cycle by the time i sold the car, and the good news is the gearbox is faultless. I also had brought 2 bottles of the additive for future use, and passed it to the new owner, since those are vital for the trouble free running of the car.
Several of my friends who have brought fit/fit aria/city cars have now used the additive and have been blessed with trouble free running. In addition several vehicle vendors i know who got the info from me have been using the additive and it seems they are happy (as they bring the additive for personal use). The bad news is that i hope they are not using this additive for cars with real gearbox troubles, as the oil will cover the problem up for a short period of time!
Overall the car served good with the following observations,
1. Fuel economy
Average in Colombo Sri lanka running where you find a color light every 100m! is around 10-11kmpl.
Average driving outstation in rather narrow roads is around 12-14kmpl
Best fuel economy when driving a long trip i got was 19.5 kpl on a hot and humid day
Best fuel economy i have seen on the dial when driving in colombo late night when the roads are deserted was 21kmpl
Worst fuel economy i have seen is when the car is idling with the AC on in traffic, and this can get bad as 4-5kmpl
a. The AC fan motor packed up (same happened to my CF4 accord i had previously) around the 60K period. I changed this from a company called Suraweera AC, they are near my house and are AC professionals. I found out that they seem to be supplying the agent as well, and their charge is much much less than the agent, specially on the labor.
b. The rear hub bearings went, this was weird and the agent themselves were surprised. Replacement was not cheap !
c. The engine mount (the infamous left mount) busted as expected, and had to be changed. This again was a common thing with this car and seems to need replacement every 30-40K. The other two mounts remain intact. The agent also mentioned that unlike others this car only had 3 mounts.
d. The front shock bushes on top had to be replaced, the agent informed me this was a common thing with this car.
e. The AC valve started a wierd squeal, like a rat !!! The agent indicated this was another common problem not with this car but with several other honda’s. I got this changed before i handed the car to the new owner. The repair was to cost less than 10K but went to 21K as the part alone was 11.5K and the labor + filling AC gas (the had to flush the gas out before doing this replacement). Well the squeal is gone, and my pocket dented. Lucky new owner
Fuel economy dropped to 9.5kmpl, and i thought this was due to carbon build up in the injectors. I got the agent to remove the injectors and clean them by hand and do the fuel injector cleaning (using the WURTH product). Removing the injectors is a messy job, unlike my older CF4, and the O-rings tend to crack and had to be replaced. Seems the O-rings are not stocked by the agent everytime so watch out. When the removed the EGR valve parth was almost 80% blocked with carbon deposits, and ye the car seems to be have been working pretty fine with this
The surprise was that the fuel economy got worse (7-8kmpl) after the treatment, and then agent then reset the computer, but then informed me that in some cars the cleaning is so effective that like a new car the fuel economy drops and it takes time before the fuel economy comes back to normal as the injectors have to get a bit of dirt it seems, wierd. However as informed by them the pull has increased so maybe its the truth. The good news was that the economy started to improve, and informed the new buyer that the best economies would take a bit of time as the 1000km has not yet been achieved after i did this cleanup. When giving i was getting 9-10kmpl in colombo city, and 13kmpl in crowed outstation so improving indeed.
So word of warning, don’t bother with the injector cleaning unless you really think it needs one. Which i guess is when the EGR path is fully blocke that the car does not accelerate smoothly. First make sure you replace the spark plugs, and here again stick to originals as the after markets seems to cause problems, and avoid the platinum one if your car is the i-DSI model. Also replace the air filter regularly, as this impacts the fuel economy pretty heavily. Again aftermarket (VIC) sold all over Sri Lanka is not good enough, so get the original. However the VIC is 1/3 the price of the original OUCH.
The chap who brought my Honda Fit is a colleague so i will keep you posted on how the car holds up with him. I also have a few more chaps who brought Honda GD1 fits in recent times at my work place, and shall see how they fare. These cars are the last batch of the GD1 Fit, and I am most keen to see if Honda fixed the issue on these transmissions, so that you can just live with the CVT oil and no additive to protect your gearbox.
