And which Engine & transmission oil is recommended for this car. Also let me know either I should do any other required maintenance work for it in the start.like air filter change or etc.

If there are any Peshawar owners of this car please recommend where do you perform your maintenance work and a good mechanic etc and from where do you get recommended engine oils in Peshawar. Also add me to the fan club (whtsapp) if there is any. My contact is: 03039529815.

Thanking in anticipation.

make them from foam sheet yourself - make sure its not an open cell foam that can soak up water.

[mshoaib432722]

Only change engine oil. Use at least 10w40 (or better) grade of any good company (Revenol, ZIC, etc). Transmission oil after 40,000km.

Sir aoa.
I have alto vxr 2007
I use havoline 20w50 but i want to replace it with liqui moly 20w50.
Can i do that?
Is it ok to do so because i think liqui moly is better than havoline 20w50.
Plz reply

It is API SL whereas Havoline is API SG conforming oil. Alto has old tappet based mechanism and newer SL, SJ standard oils have lower ZDDP (zinc) content which increases cam wear and tappet wear.

In easier words, in long run engine head's life will be reduced, car would become more noisy and more frequent tappet adjustment would be needed.

There won't be any observable difference except placebo effect due to pricier meaning better mentality.

Better stick to your current oil or similar one.

My Toyota Starlet ' s rear hatch takes too much force to open and close.But it stays in open position. It does not falldown. What could be the reason?

@Xulfiqar, assalamo alaikum Sirs... Engine Oil query here. I have been using 10W30 Mineral from honda in my Civic 8th gen. the milegae is 90,000 km... Will it be safe to use 5W40 Shell Helix Ultra in my car? Problem is, I have already bought it today and have to change engine oil tomorrow. I had been thinking of converting to full synthetic...

After searching some, I think 5 will flow better at cold temperatures which is required at startup... And 40 will be more stable at higher temperatures than 30, so it will continue providing lubrication at the normal engine temperature... I am just worried that perhaps it might lead to engine wear and tear in the long run. I dont know..

Please help me ...

Kuch nahi hoga engine ko. Bay-dharak istemaal karo 5w40.

[jatt.zaildar]

chalein shukriya.... going to use it today....

Well... brother I have changed to 5W40 Shell fully synthetic and so far satisfied... But I have suddenly encountered another problem... Previously my car used to give me 11,12 km/lit inside Islamabad city with some spirited driving.. But after the oil change (150 km ago) the fuel average has suddenly dropped to 10.7 km/lit and that too on GT road + Kashmir highway drive (just 10 km inside sectors)..

Furthermore the car feels struggling. I mean at 80 kmh the rpm was 1500 previously.. Now I need to keep rpm at 2000 rpm usually.... I check tire pressure daily, so it is not the cause... I am wondering what might be the cause of this sudden and adverse increase in fuel consumption... What do you think might be causing this?

[mshoaib432722]

Check oil level everyday. If it stays contant then problem has nothing to do with oil.
For fuel average problem, use some different petrol station to fill up your tank next time. Sometimes petrol quality is shit on some stations.

[jatt.zaildar]

I suspected the same... I mean petrol station. I had filled up my tank from a just-opened hascol pump on GT road. and I think petrol quality is the cause of all this... Today fill the tank from my trusted pump and will see in next few days....

Bro,, one thing more... Honda supplies oil in 3.7 lit package... I changed oil filter + oil and put appx 3.7 lit out of 4 lit bottle of shell.... But still the dipstick is showing 1 point less. So it means I should put full bottle in the engine? What is the actual engine oil capacity of Civic - R18A....? ...

[mshoaib432722]

Civic r18 series engine = 3.7 litre oil + 0.2 litre in oil filter.
Fill the oil up to the dipstick full mark.

thank you brother. really helpful site.

2 flushes later. System is clean and working A ok with no sign of oil contamination and coolant alhamdulillah is maintaining level even after hard driving. Cost saved: 60k engine swap. Blame: shitty mechanics who dont clean the cooling system to save time after opening the head of the engine. Did everything myself.
