With respect to the topic, my contribution is this:

1. Remove all those nonsense spoilers that you attach to the car yourself. They cause drag and make your engine work harder than normal.

2. If you use a manual car, learn to drive on neutral while going downhill.

Please, I am currently using Hardex Gold Engine oil for my Toyota Corolla, I change oil every 6months, I only drive to church and sometimes to work, most times it's parked. Kindly let me know if this oil is okay


Pls recommend a good new tyre for me and the price.

I currently live in Benin City. Thanks

Bad Driving habits.


* Vehicle idling
Starting the car and leaving it to idle for 10-15 mins before leaving the house.... It's gone! Start the car, put it in drive and drive , don't waste 10-15mins of fuel.

* Aggressive Driving

Let me tell a short story, on my 1.4L 2009 Kia Rio I traveled from Lagos to Benin on 18Litres driving at a max speed of 100km/h I filled up in Benin to confirm.

Repeat of same journey took 30L driving at a max of 140km/h and aggressively.

Slow consistent driving , and not powering uphill will save you a lot on petrol, avoid the quick races, remember that for each race you win or loose, you lost about ₦500 , slap the throttle pedal gently .

* Google maps .

I use Google maps for the shortest of distances, I always avoid traffic and choose the best routes, learn to use Google maps with the traffic prompts on so you can make better decisions. Also teach your drivers to use the map too.


* Avoid fuel additives.

Those cans they sell in the petrol station will not get you any better MPG, use the money to buy petrol, it will also not keep your system clean.

Please tell us one highway in Anambra where one can drive for at least 30 minutes without encountering any of the above mentioned..


Oga answer the question first ?

Me too I'm from Anambra and i reside here in Awka

You must really be a bad mechanic. So because of 600 naira fuel, I should start my car immediately and start driving at full speed without allowing my engine to warm up about, or even telling your clients to drive slow if they happen not to warm up. I pity those who listens to your advice. You're among those bad mechanic that fixed one and destroys 4

MrHighSea:
any engine more than 1.5L OYO
Travelling through more than 2 states, GiG

Use original plugs

Coasting downhill on neutral with a manual transmission will not save you fuel but work the other way round and it's equally not safe.
You need that boosted pressure from the engine for your brakes to work well, besides modern cars are designed with a fuel cut off system when coasting in gear.
It's advisable to just leave the car in the appropriate gear when coasting downhill.

jceesquare:
Using 20W50 oil viscosity will eat deep into your fuel because of additional efforts to move parts within the engine caused by friction from the oil

FILEBE:
@Gazzuzz. You didn't talk about closing any exhaust leaks. And then about thr catalyst.

That was how my car started bringing the P2A00 error code when scanned o. Something that has to do with o2 sensor bank 1 sensor 1 . But my readings says the sensor is okay. I am suspecting the back 1 sensor 2. Then panel beater hear my car sound come talk say dem suppose put muffler inside thr exhaust pot. I still dey reason how to solve the problems

GAZZUZZ:


Difference is very minimal, reason I didn't bring it up

jceesquare:

True but makes more sense when most people drive off immediately after starting the car with fan running directly sir.

GAZZUZZ:


Considering we live in temps averaging 25-40deg Celcius, I see no reason why there should be a problem sir.

jceesquare:

Another true submission sir.
But from my personal experience, fuel economy gets affected mostly in the morning when temp is cold (that's when most people leave for work), fan running directly (possibly with aftermarket radiator aka double cell), and engine running on thicker oil.
I've seen cars running all day with the temp remaining close to the bottom.

Manuella4ace:

If you drive aggressively, your fuel go finish.

No more James Bond, na to drive like village head sure pass now

what could be wrong with my car? I have to top up coolant every three days else when in traffic and not moving my car temperature just keeps rising to red line. The moment I move, it comes down to the middle. When there is coolant, it doesn’t happen.

Car is a Camry 2003

GAZZUZZ:


Let's split the matter into parts so we don't loose focus.


A. Engine Electronics

* Buy a personal scan tool.

Buy a portable scanner so check for errors when they appear, if you don't know what the codes mean, enter into cartalk, post the codes and we will guide accordingly.

Some vehicles have had their warning lights removed by technicians and card dealers, this is the time to restore and scan.

* Scan code results.

Scan code results that have to do with the following will seriously affect your vehicle fuel efficiency by as much as 40-50percent.

Engine running rich or lean codes
02 sensor codes
P0128 coolant threshold
All timing related codes
Evaporative emission codes
Catalytic converter codes
Engine misfires
MAF codes
Exhaust gas recirculation codes
Variable timing codes
VTech codes
Boost pressure codes

There are more, but these are the common ones. Have them solved properly (not by clearing code) and you will save a lot on petrol.


B. Suspension

* Tyre pressures : keep tyre pressures at recommended levels (check drivers door or fuel tank cover) vehicles with low tyre pressures, consume more fuel than vehicles with the right tyre pressures.

* Wheel alignment, Ensure your alignment is on point, when you have front wheels fighting with them selves and asphalt, it causes unwanted drag, which results in more fuel consumption.

* Keep windows up when on long trips , this will reduce the amount of wind resistance the car makes, less drag more savings on fuel.

* Aerodynamics, the abuse of vehicle suspension in the name of raising vehicle height usually has consequences when done poorly, when you have the head up and tail down, you are fighting to get through the air, and constantly loosing efficiency to wind resistance. Same thing happens when you load 4 adults at the back and fill the trunk with load

* Sticky brakes . brake binding is a situation where the vehicle is being held down by the brake pads without application of the brake pedal. Could be caused by work done on the brake switch near brake pedal, rusted calliper pins rusted calliper prisons, faulty abs pump. Whatever the case, if you get home, splash some water on each wheel, if you have instant steam from any wheel it is binding and should be checked .

C. Service and Maintenance


* Filters sparkplugs and MAF.

Some cars never get a replacement engine air filter all their days in Nigeria , replace your engine air filter with each oil change , clean and re gap your sparkplugs to the required spark gap.

Carefuly clean MAF sensor with the required MAF cleaner, please do not do MAF cleaning unless you are sure it is required, it is not an item to clean regularly.

* Fuel Pressure

We don't have very clean petrol, so if your car begins to feel lazy especially after a long trip, might be time to check the fuel filter and strainer inside the fuel tank , if clogged replace, you will get better miles per gallon. In most vehicles, low fuel pressure will not show up as an error when scanned.

* Blocked Exhaust system.

The inability of exist gasses to quickly leave the engine into the atmosphere, will cost you more on petrol.

Some vehicles are naturally predisposed to catalyst blockage e.g Honda , Acura , Ford , Kia , Hyundai. If your vehicle is one of those you might want to get it checked out, also if your catalyst has been stolen in the past and was refilled will wire mesh or a catalyst clone which also gets blocked easily you should have it checked.

Know your vehicle, if a vehicle starts dragging, something is off and should be checked . Blockages in exhaust in exhaust systems will not show up on scan results for most vehicles, it takes a smart tech/owner to detect it in early stages.

Please what does this to code mean on Toyota Camry 2008

P0012
P0420

GAZZUZZ:





Code P0012 Toyota Camshaft Position 'A' Timing Over-Retarded

You might be able to fix this issue by replacing the camshaft timing oil control valve in pic below .

For the P0420, just replace the catalytic converter in the exhaust manifold .
