What is the ACEA "2 Engine Tests, 2.8 Wear, Viscosity Stability, Oil Consuption "?There are wear and tear of cam cylinder.
There, there, but if you read carefully you will see that the limits the same for all A andB categories, and that achievement will mean that oil is not a disaster on this issueand therefore a "special treat" to be displayed any better oil and better than everbecause the light example to test the ACEA standard wear a xx% improvement (ie, less wear and tear).
There is a test engine under 2.3 for C ACEA standards with similar comments.
And so on. The story can and stretch but it's for a special article on standards and a special article on the ACEA standards, and hard to catch it before the end of the year, but we'll see.
ACEA C standards
These are standards for gasoline and diesels that have equipment for post-treatment of exhaust gases. Of course, true for Euro IV engines (and V). When diesel enginesare in the post treatment equipment includes DPF (Diesel Particulate Filter) and the gasoline TWC (Three Way Catalyst). In both cases these devices extend the oil lifevek.All is "low SAPS" oils and fuel economy. By the way except for C4 requirementshave remained relatively low HTHS *, noting that the C3 (with C4) designed for high performance cars. For all oils that meet the applicable standards of C notes to pay attention to older cars (engine) because it may not be suitable for them. We shouldadd that if any of these oils are not suitable for mixing with other oils, but only with each other, again with caution, C1 and C2 can not both together, but mixing with C4type of oil.
* Just because the relative C1 and C2 classes include low viscosity for example. 0W-20 (30) or max. 5W-30 viscosity and with the value goes lower HTHS viscosity. C3are often 0W-40 or even 5W-40 viscosity.
Postscript
Mid-SAPS oil (among other things) must have a sulphated ash below 0.8%, whileLow-SAPS below 0.5%. ACEA C1 requires only condition for the Low-SAPS andless than 0.5% ash, while C2 and C3 "tolerate" and Mid-SAPS specification, but not more than that.
