In terms of performance or efficiency, they would continue unaffected just like the multitude of EU4 diesel vehicles running happily on EU6 fuel. Performance or efficiency gains will be primarily for direct injection turbo petrols (higher RON, lesser sulphur), and those diesel engines originally developed with EU6 in mind, but later de-tuned to accept BS4 grade fuel.
They are also unlikely to benefit from longer service intervals by using newer long life engine oils (this is applicable to BS4 VW TDIs also). I do not know specifically about the MJD/TDCI in EU, but VW TDIs that have flexible (long) service intervals also have additional oil quality sensors and algorithms that monitor and suggest the length of the flexible/extended service interval depending on driving patterns / vehicle operating conditions etc. Our cars don't have that yet (at least in the affordable models).
P.S: We have two cars in the family that tend to gain with RON 95. Still waiting Quote:
Easier said than done.
Even today, even in Major metro cities, often we get such news about cheating pumps.

Quite true. However I see some positives in the recent strict adherence of BS3 sale/registration, and now removing the FAME subsidy for mild-hybrids. Seems someone or something has gotten into the system and make them think more than just blanket bans. I hope the same caution is exercised on the oil companies also to make them ensure fuel quality and prevent adulteration. Wishful thinking |
