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.

Release date: 02 December 2009

BP Australia advised its customers today that ongoing issues at its supply terminals have delayed the company’s ability to restock a number of its service stations in the Perth, Adelaide and Brisbane areas with BP Ultimate diesel.

Supplies of regular diesel are not affected.

BP is putting a number of measures in place to ease the supply situation. One immediate action is to replace BP Ultimate diesel with regular diesel at all affected sites.

Accompanying this change will be point of sale information to ensure customers are made aware that only regular diesel is being supplied.

BP regrets any inconvenience caused and will update customers as and when BP Ultimate diesel sales recommence.

Doesn't affect Sydney - only because it's not available here
