I bought a 97 Volvo 960 66K miles with a 2.9 Liter I6 in Feb 2005. For some reason the last oil change before selling the car the previous owner filled it with Castrol synthetic. Before the 65K service it had 5K dino OCI. I got all the service records with the car. I ran that oil for 2,500 miles before dumping it and starting my Auto-Rx treatment. Once the full treatment was done I filled the car with M1 10W30 and 6 oz's of Lube control. Well it has been 3700 miles and 6 months later, I got the oil changed yesterday. Yes I know I could have gone a lot longer but I felt safer by following the minimum OCI's. I got one heck of a surprise when the oil filter was pulled. The oil that was draining from the filter mount was extremely black. When the oil pan plug was removed what came out confirmed what I saw earlier.
From what I saw yesterday confirms that Lube Control does clean very well. Those 3700 miles were 90% highway btw.
I run my 87 Volvo Turbo with M1 10W30 and a maintenance dose of Auto-Rx. Even at 5K miles and all short trip city driving (less than 3 miles) I never have seen the oil come out this dark.
I'll be interested to see in October how dark the oil I put in today looks. I know, I know, I should have done an oil analysis on the oil but I forgot all about it.
The gas mileage jumped about 1.1 miles per gallon on the highway and the engine smoothed out a lot after doing the Auto-Rx treatment on the car. Plus after I changed the oil yesterday the motor was much more quiet with the new oil and LC.
