Bahria shell is a cheat thats what i also heard from my circle. Never tried it.
Sometimes small engines especially non-EFI cars or cars tuned on CNG dont accept high rated fuel resulting wrong mixture which makes engine knock. i heard from few people that after running their car on high-octane engine starts to knock.
wao. this is really a good news. Modren diesel engines need Euro standard Diesel.
I ve been using shell and works fine with Baleno 99 and corolla 97 JDM.
As an experiment i changed to Total (near chaklala scheme 3 bridge) and it started knocking.
I never used it again!
Good repo Caltex filling station is the best fuel 1 can get!
here in karachi , ayesha manzil total parco is one of the better ones , i would prefer that petrol station .
my frnd owns a total pump.. quality is so-so... so i go for shell.. mainly becoz of availability of high-octane.
Total Customer Services and Fuel quality is better than the Shell and PSO. Our company just contracted with Total due to their best customer services for more than 250+ employees. We have started getting reviews from employees and 80 percent are satisfied. Furthermore Total Fuel Card is widely accepted on highways whereas Shell fuel pumps (previous contract) don't allow.
