jdlc Posted March 14, 2010 Report Share Posted March 14, 2010 Have to disagree about the additives and what not. High detergent oil is going to be safer than dumping a solvent in the crankcase and expecting safe and reliable results. You never know what you might dislodge that has been sitting quietly for years... (dino oil car) This is why the pitch of AutoRx is slow-cleaning, they know too well that strong detergent applied to 'sludged up' engine is no good. I tried this product with good result - the oil takes longer to darken after the treatment. One could say that's not the indicator of good oil - but the again, if your oil is muddy only weeks after oil-change, then something is not right. If your car has always had synthetic, it is probably WILL BE in really good condition engine-cleanliness wise... Case in point, my V70 NA with 160k - Mobil1 since new (well, after I stopped taking it to dealer for oil change, lol). Picture was taken a while back, but not much have changed, still looks like that today. Link to comment Share on other sites More sharing options...
