Suggestions for handling new car

[jklodhi]

All fuel of Total , Altron and shell is Ron 92 or above.

City has no such requirement of Ron 92.

What should the undercoat be done for? What does it do?

AFAIK in theory, Under-coat prevents corrosion in the under surface of car and dampens noise produced by the collision of under surface with road debris

[mbadarmunir]

City has no such requirement of Ron 92.

But still using 92 or 97 Ron should be preferred or no? (For better mileage, better combustion etc.)

[suhaibayaz]

I read a Harvard study which concluded that using "Premium" fuel does not give any advantage regarding mileage or acceleration, compared to recommended fuel by your auto maker.

So effectively its just burning extra cash.

You can google and do your research though, always better to arrive at conclusions yourself.

[mbadarmunir]

I do agree with that as my search on web concluded the same. But basic fuel category in all pumps has 92 RON I guess. So is there any harm in using higher RON fuel (92) if it is the least option available?

[suhaibayaz]

I dont think there is any "harm" or damage apart from it being mildly expensive. Pakistan had very low RON fuel compared to developed or developing countries, I still dont understand how they are selling RON 92 with fuel coming from same refineries. Refineries dont upgrade overnight.

[jklodhi]

Fuel is being imported for some suppliers and parco and attock have upgraded their systems.

I am not sure what you read. A link to reference it would be welcome.

AFAIK, you should follow what car manufacturers guidance is. If they designed the engine with lower fuel RON in mind, it is the right choice. A lower RON engine can use the other fuel, but there will be no benefits, instead loss of money.

Usually, certain cars come with high pressure combustion engines, and thus they require higher RON fuel to burn properly. These engines can run on lower RON fuel too, but due to unharmonised fuel burning, produce a knocking sound.

There is science in this.

Just care about yourself and humans, instead of going deep into car care. These all things are made to facilitate us, not going to think so deep before getting it. new car just need to be replace engine oil and filters, after each 5k, else nothing to do and worry about, just relax and enjoy drive.

keyboard warriors at this very forum may go one step ahead and suggest you using JET FUEL randomly to keep engine clean & efficient. click cause no money but fuel cost significant amount at every tank topping.

stick to "supreme" which is 90+ RON rating & engines in PKDM cars can handle nicely, 90+ ( 90 above rating ) RON fuel is sold by shell, pso, total, attock, hascol across Pakistan.

every time you change engine oil brand change the oil filter as well.

Till such time warranty expire, stick to Honda 3S shop for oil & filter changes.

[suhaibayaz]

What capsat said. You read too much into my post. All I said was if your engine requirement is 87RON, using 98RON yields no added benefit. Unless your car comes with 98 as recommended fuel

JET Fuel ? Elaborate please

[capsat]

Jet fuel is a clear to straw-colored fuel, based on either an unleaded kerosene (Jet A-1), or a naphtha-kerosene blend (Jet B). It is similar to diesel fuel, and can be used in either compression ignition engines or turbine engines. highly combustible producing extra ordinary kinetic enegry

[z.u.m.a]

@capsat Is it available commercially? Where can I find it and at what intervals is its usage recommended ?

Thanks

[mbadarmunir]

Lolz. @z.u.m.a Are you being sarcastic or you really meant it?
@capsat, I got that using high RON won't give any benefit. My question was that will using 90+ Ron fuel instead of recommended 87 cause any harm as it is the standard minimum fuel now. It is now clear that using 92 Ron is ok. I'll be using that.

[z.u.m.a]

Oh crap My bad!
Didn't read the initial line properly so...

[mbadarmunir]

One more question please. I opted for rear speakers from Honda as well. The dealer neither showed any interest nor he guided properly. He told me that I could purchase these speakers from market after getting the car. If I insist on buying these from them, I could pay at the time of delivery and get those installed then. Can anybody recommend some good speakers (their model and specs etc.) and their price? I would buy them from Montgomery road. Any good shop there?

[mbadarmunir]

Got it delivered by the tentative date. Have driven it 2.2k kms in 3 weeks. Was surprised to see the honda guy filling up the coolant by tap water at 1k km service. On inquiry, he said that this small amount of refilling doesn't matter even if you use tap water. Wasn't a bit satisfied with the answer though.

[z.u.m.a]

It matters or not.But they should follow the right procedure.btw Tap water does cause problems in cooling system.
