Which Oil weight would be suitable for peak performance city driving conditions + max mpg, respectively for a Diesel Vehicle ?
5w30/40 Vs. 10w40 Vs. 15w40 Vs. 20w50
Mainly market competitors & suitable oils examples liked by public in pakistan market:
1. Shell Rimula r4 15w40
2. Delo Gold Ultra 15w40
These two oils are well-known for heavy usage & beating. but city driving does'nt requires that much beating.
some international consumers consider Petrol version of OILS for city driving, also light off-roading, example:
1. Shell Helix
2. Caltex Havoline
these OILs in Pakistan are known to use for PETROL vehicles only.
but both these oils are also API SN/CF, if you read the details at the back of their respective boxes , which means it is suitable for Diesel vehicles, as well as they are described in their details as consumed by blow-by re-circulation vehicles with turbo & naturally aspirated vehicles etc etc, everything mentioned there. Despite all these detailed specs, people still say & the guys at the pump claim its only for PETROL vehicles.
There is lots of confusion going on, which OIL is precisely & accurately to be used for the respective vehicle to get the most out of it, which includes peak performance with max mpg as well as good engine lubrication.
Not less than 0 Degree Celsius max ; Not more than 40 Degree Celsius max
City driving conditions mainly include:
- Stop-n-go traffic
- A/C running continuously
- Short trips
- Longer idling
Need everyone to share their respective experiences and knowledge.
ALLAH BLESS Everyone ! (Ameen )
