I just went out to the garage and removed my dipstick and rubbed it over one finger. Then I went to a brand new bottle of Redline 10W40 and put the new product on another finger. The used oil is definately a darker shade, but it looks just like fresh new petroleum oil and you can see through it. I had no idea that synthetic was so clear when new! I am using the standard Redline for street use NOT the race oil which does NOT have the detergent package. Redline oils have much higher thermal stability than petroleum based oils and also better than many other synthetics. The high temperature stability insures that there is no contribution to sludge from oxidized oil. Also, Redline uses large amounts of dispersant chemistry which encircles the combustion particles and prevents them from coagulating with others and settle out in the lubrication system. This feature is what gives good synthetics the "long drain" intervals. Redlines tests have shown their synthetic oils to last 25,000 miles in field tests!!! No, I'm not advocating that, but they do recommend a change between 12-18K miles, depending on the type of service. If the engine is worn and considerable stop and go driving is involved, then they recommend 10-12K between changes. Also no matter what, change the oil once a year irregardless of mileage.
