Thanks. The data is well presented.According to the link in this post, European diesel has a much lower scar rating than North America's.
Trouble is, only a few samples from each region/country, and the failure rate of CR fuel pumps should also get such a nice orderly reporting:
The survey covers different refineries but doesn't seem to control for brand specific additives (Chevron vs Shell vs unbranded etc.):This year Infineum collected 381 samples from 42 countries, which were analysed for 14 parameters including: sulphur, lubricity, cold filter plugging point and fatty acid methyl ester (FAME) content.
Its still a very nice presentation that makes no unsubstantiated claims.Samples need to be representative of the diesel purchased by the average consumer so they are gathered from service stations by Infineum colleagues at local area offices. As a general principle, Infineum tries to get one sample that represents the production from each refinery or region in a given country. To minimise the possibility of taking multiple samples from a single refinery, knowledge of local exchange agreements and distribution systems is used to select where each sample is collected. For the larger diesel consuming countries, this procedure results in samples that represent a reasonable average of the overall quality. However, for smaller countries or specific producers, spot sampling over a short period of time will effectively only provide a snapshot of production quality, with data derived from only one or two samples. This can make it more difficult to evaluate trends with any accuracy.
