Hints to help protect your car
Modern Euro Cars and Unleaded Petrol
|Fuels are not just fuels. Petroleum companies give us a choice of higher octane fuels for a reason.|
A lot of car owners do not realise that european cars need high octane fuel. I get new customers on a regular basis coming in complaining that their car runs rough, is hard to start and feels sluggish. All these things can be caused by poor fuel, and if you're running under 95 ron fuel, this is something you can experience very often. On top of this there are the unseen things it does inside your motor which aren't visible until it's too late and serious damage has occurred. Next time you think your saving money on that cheap fuel, consider this.
As this fuel does not burn as well as higher octane fuel, you get worse fuel economy.
Modern cars have a sensor, like a microphone, bolted to the engine block. Low octane fuel can pre-ignite, indicated by a ping or rattle and this sound is detected by the sensor. The engine management system responds by retarding the engine's timing which reduces power and worsens fuel consumption. Using a quality high octane fuel will reduce the likelihood of this occurring and your vehicle will, therefore, run cleaner with better power output and better fuel consumption.
Why Transmission Oil should be replaced
|Do you know if you auto oil has ever been changed?|
If its always been serviced by a dealer,
there is a very high chance that its never been changed, as most manufactures say they are sealed for life.
Renault have had electronic controled automatic transmissions since the 60's and then got a bad name in the 90's where you would always get told,
"dont buy an auto renault". Well this is a bit of a myth. The main reason for the untimely demise of those early units, was not the auto,
it was how they were maintained or, more to the point, how they weren't.
Most workshops did not know how to change and reset the oil, so it was never replaced. Even when it was they often used the wrong oil.
And as we know, oils ain't oils. Either way the poor auto would basically cook itself inside out. Ever since day one, Auto Paris has made it
regular service policy to change all our transmission oils every 20,000 or every 12 months. We've seen a 95 percent drop in transmission
failures which saves you alot of pain and money in the long run!
They also shift smoother and at least doubles the life of it.
This is what we do to every automatic car that we service, as the transmission in Renault, Peugeot and Citroen models all use the same transmission.
Many new customers have rung the next day asking "what have you done to my car", as they can't believe that changing the auto oil could have made
such a difference in the drivability of their car.
Something else about fuel....
|Some facts you might not know about modern fuels.... |
We have come across another new pain that you should all know about ethanol based fuels!!
We had a little Renault Kangoo come in last week that wouldn't start. After we checked for correct cam timing and for fault codes, it sounded like it did not have a lot of compression. We then completed a compression test where we found it to have little to no compression. In the end we removed the cylinder head from the block as there was nothing else it could be except for valves. When we inspected the head we found all the exhaust valves to be burnt out which caused them not to seal. After doing some research, we found that the fuel tank never goes under half, and is filled up with what the customer thought was good fuel but it contained ethanol. Due to current unleaded fuel really only having life span of a month and the fact that ethanol absorbs moisture, the old fuel in the bottom half of the tank had become increasingly concentrated with ethanol and moisture. Since each tank had not been run till low, the concentrated ethanol / moisture caused major engine damage! So if you are using a ethanol fuel, don't use every tank, instead say two tanks of ethanol to one without, and try and run until the low fuel light comes on or close before refilling, to keep fuel contamination (ethanol concentration) to a minimum. The injector cleaner we have will help break ethanol concentration down too, but this car was so bad we had to drain the entire fuel tank.
