I went to my local O'Reilly for royal purple 20w-50 last night and was I ever surprised when they told me the list price was $18.63 per quart! I was quite shocked when he rang up the 4 quarts and wanted like $75.00. That was with the 10w30 on the shelf for $7.29. The 20w50 was hiding behind the counter.
Any one else had an experience like this? I was able to talk them down to 9 bucks but you know the price of oil is going up. I don't think I am headed back there in the near future! i do like the oil. In 2,500 miles last year there appeared to be no wear as evidenced by a nice clean filter when cut open and valves that needed no adjustment. Just had to vent. Jule |

I've learned that the oil testing can be way off. The levels we got results back for say Swepco, was about half what the manufacturer's minimum specs are. It's a matter of retesting, testing again, and once more, with different labs. Eventually I will have enough data points between Staveley, Blackstone, and Butler to have my wife do a statistical analysis and come up with "corrected figures" that are comparable to one another. Until then, it's more or less trending....
Same thing happened with Redline and Brad Penn - I was able to speak with their chemists directly and they told me the actual min levels with Redline, Brad Penn, and Swepco, since all three called me and offered the info straight up - no twisting of the arm required. I have about double the oils tested from what is listed on the site - I haven't finished updating the excel file, but once I have time, I might just post the excel file for everyone to download. There are other #'s not shared or even tested for. I was very impressed to see that Brad Penn had done the ASTM D test for determining the HTHS vis. @ 150C. Most companies don't share that number or even test for it, since it's really a European ACEA requirement of the A1, A3, A5 sequences. I am updating the table also to add flashpoint and the HTHS # if I can get it, and TBN. |
