Hi, I did a Blackstone oil report the last 2 years around the same mileage, with roughly the same car usage; heavy street traffic in Boston combined with some highway runs, and one track day on both oils. Here is the difference between the 2 reports. See the very high Molybdenum content on Redline for which Blackstone is not phased at all... and their comments below. Left column Amsoil, right column Redline. Image Unavailable, Please Login Comments on my question about high Molybdenum content @Redline: "As far as Molybdenum goes, Redline adds quite a bit of that element, along with boron, calcium, and zinc for purposes of anti-wear and more calcium as a detergent/dispersant compared to the Amsoil 5W/40 which just carries a lighter additive package. From what I'm seeing between the two reports, both did well to protect the engine. We've found that differences in additive packages don't make an appreciable difference in how an oil protects an engine. " Both oils were 5w-40 weights. I now have Mobil 1 0w-40 Euro spec and will do a report at 2000 miles to compare... stand by ( another year or so )
For what it's worth, I found Amsoil to be a noisier engine than Redline, from the seat of the pants.. or it could just be my old age decaying hearing. Whatever the additives.
Interesting that the viscosity didn't hold up well with small.mileage on Amsol Sent from my moto g power using Tapatalk
I'll be interested to see what the Mobile 1 is like. Since Redline has little use for distribution east of the Sierras I switched to mostly Mobile 1 ten years ago.
An interesting video from PCA, ALL synthetic oil is produced by 3 companies and the additives are produced by 4 companies. You might just be comparing the same oil with slightly different additives... Now you know what the INEOS decal is on the Mercedes AMG F1 cars is! Image Unavailable, Please Login
Good info from Mr. Lake Speed Jr. I thought his data about how it takes multiple OCIs for the residual additives to completely switch when changing oils was particularly interesting.
Additives don't make or break oil viscosity in time, or I don't think so. All that talk is just ... talk. Oil reports are facts.
