1qt size in newer version, and while it is still good, it is definiately more vanilla.
True. If it's the same in the US as Canada, we had 1L bottles of ESP Formula 5w30. When they came out with the newest version, simply called ESP 5w30, it is now in 1 quart bottles here.
What I liked about the original version was it's lower sulfated ash (0.6% vs 0.8%) it's higher HTHS (3.58 vs 3.5), higher viscosity at 100c (12.1 vs 11.8) and it's lower noack (5.6% vs 7.9%) But it still has the same certifications so I have no doubt it's still a very good oil and when my stash of ESP Formula 5w30 runs out in 5 years I'll switch to the newer version (which might be tweaked some more by then)
Don't forget that ridiculous flash point of old version.
Was that a D92 or D93 reading, though?
Somebody on here was kind enough to point out that D93 tends to give substantially lower flashpoint results that can't be compared directly to those from D92.
The 254c flashpoint is from ASTM D92

They are clearing inventory at local CT and I got 5 quarts of the old ESP @ 9.91$ (canadian) per litre.
They still have 6 quarts left... I'm tempted...
