Is there is any advantage using Speed petrol or Speed Diesel
Ordinary petrol has an octane number around 85. Speed petrol has an octane number of around 93 or even higher. Higher octane number is required when compression ratio of the engine is higher. Because of higher octane number pre-ignition is avoided. Thus giving a better performance. Sports vehicles have higher compression ratio. Hence the drivers of these use Speed petrol.
In an ordinary engine, speed petrol might not have that big of an advantage but as compression ratio increases one requires a petrol which can cope up.
High Speed Diesel has good cetane number 56-60 whereas normal diesel has cetane number ranging from 45-55. So, High Speed Diesel have better combustion thereby achieving good performance as well as cleaner emissions. Now a days, High Speed Diesel has special additives that even cleans the carbon deposits on fuel injector.
Hi-Speed Diesel contains detergents that enhance combustion through a process of cleaning up of fuel injectors that are blocked with harmful deposits. This improves spray pattern and prevents the injectors from "dribbling" with diesel. These detergents not only clean the injectors but also prevent the formation of new deposits making it work as good as new. HSD is normally used as a fuel for high speed diesel engines operating above 750 r.p.m. i.e. buses, lorries, generating sets, locomotive, pumping sets etc. Gas Turbines requiring distillate fuels normally make use of HSD as fuel.
I PRESENTLY OWN A SKODA SUPERB. WANT TO BUY A 7 SEATER SUV. THE FORD ENDEAVOUR WITH ITS RICH FEATURE INTERESTS ME. HOWEVER, MY CAR TRAVEL ON AN AVERAGE IS NEVER MORE THAN 6000 KMS PER YEAR. SHOULD I GO FOR THE DIESEL SUV, OR OPT FOR THE TOYOTA FORTUNER? THANKS.
Hey, we would suggest you to go for the Endeavour 2.2 here as it is Cheaper, optional automatic and good for limited usage. Fortuner petrol indeed is a good option. However, The Endeavour diesel is cheaper to buy compared to the Fortuner petrol by nearly 2 lakh for the automatic Trend variant. Infact, the top-spec Endeavour 2.2 AT 4x2 is on par with the petrol Fortuner automatic also Fortuner is more expensive and would not deliver mileage as the Endeavor. Hence, Endeavor is a better deal here. Click here to check out the comparison.
Hey, if you drive for 50 kms in a day, we would suggest you to go for a diesel variant as your monthly running can be more than 1500 kms. The diesel variant though would be expensive to maintain and would cost you more than the petrol variant but you will be able to cover that cost while you drive it.

The reserve fuel tank capacity is around 7 litres. Click here to know all about it.
