Best Diesel: Shell? Caltex? BP? Mobil?

**stewarthou** · 23-03-2009, 01:01 AM

I just did some researches on different diesels (normal diesel, no bio, no premium), the result is shown below(No Mobil Diesel Data)

PROPERTIES -[Shell]- -[Caltex]- -[BP]-
Sulfur -[8]- -[<=10]- -[<=10]-
Flash Point -[79]- -[>=61]- -[No Data]-
Density -[0.82 – 0.85]- -[0.82-0.86]- -[0.82-0.85]-
Cetane -[49]- -[>=46]- -[51, >=46]-
Lubricity -[400]- -[<=460]- [<=460]-

Which one is best for performance and economy?

I use BP and Shell as second choice. The long term fuel economy in my T5 is - 9.5L/100km (very short trips and fully loaded). Done 65k now.

New research result:
higher sulfur = more smoke(bad for environment) = higher Lubricity(good for engine)
higher cetane = more power
Thus it seems BP is the best.

I use BP, get worse economy out of Caltex.

Shell is best for economy for me as I get $0.08 per litre off at Coles express so works out best in terms of cents per km. $0.04 shopadocket plus $0.04 voucher that comes with statement when I pay with Coles mastercard.

2 Coles outlets in Townsville go very close to matching the best el cheapo independant price while the other 2 are $0.10 dearer so they miss out on my business.

With Cetain so close to BP I cannot tell the difference so performance is not an issue for me.

the bp around the corner from me sells bp ultimate diesel and its all i ever use. they're not more expensive than other bp's who sell the regular diesel.
