What in the worlds name have you all been smoking???
All this happening right under your nose??? :S
Honda MTF is about 1.1k per litre. And the iDSI takes about 1.8L. Yes, only 1.8L on a normal drain. If changing it at 60~80K Kms is expensive, then God knows whats cheaper.
Your car is still under warrenty and you are worried if Honda Engine Oil is good enough?? You want to risk warrenty with some other option??
Dont ask the dealership. Just go with the service manual Honda gave you with the car.
I am simply stunned about your concepts of tyres and thier expected benefits. May I suggest some tractor tyres??? Like the ones used in Massey Ferguson?? Hopefully they shall meet all your needs.
1. Road Clearance (more height, good road clearance especially when driving with 5 ppl on board)
Tyres dont behave like shock/damper spacers. If you try to increase profile as an excuse to increase height, you will most likely hit the wheel arch when fully loaded with 5 people.
2. Fuel efficiency (more circumference, less rounds per min and less fuel consumption)
Physics and Thermodynamics dont work in the way as imagination can say. Each car has all the aspects covered in design phase about the target cruise speed, target rpm range, target timing and fueling maps for best economy and optimum resposne. You change that and you drive the car in a range NOT IN ITS OPTIMUM BAND.
Ofcourse this happens all on a microlevel sometimes. But it wont bring any good mileage.
3. Comfort (more width, more shock tyres will absorb and more comfortable ride becomes)
Referring to Point #2, The terms FUEL Efficiency and MORE Width, dont sound right together. Thats a short answer to this misconception.
I am sure your mechanic must be educated and qualified enough about the subject of friction modifiers
and other additives added by each manufacturer for their specific vehicles. It does take a sound knowledge to discredit an OEM product (oil in this case) right???
Yes CALTEX makes good products. But this is no excuse to use it when you have OEM available.
If only there existed a world where bearing could be repaired (A)
Janab, please google what a bearing is. Then search about where its put in an alternator. Then search about how to replace in case of failure. And finally THINK about whether you'ld want to install a REPAIRED bearing after all the effort???
You should be lucky there is an option of bearing replacement. What if the manufacturer asked you to replace the whole alternator??
