Someone sent me a PM about their coolant being blue instead of the normal green / yellow... This is the coolant the mfg. uses in the car when it is shipped from Germany. It is manufactured by ATE, who also makes great racing brake fluid. Don't worry about the blue color... It's normal for this product...

They also make a race spec. brake fluid (ATE SUPER BLUE) that is sold in both blue and red. I flush my brake fluid every few months and it helps to alternate the colors so I know when the system has been flushed completely.

All I can say is change your oil and coolant more frequently than the mfg. recommends and your engine will stay solid... And also, add a pint of Marvel Mystery oil the day before you change the oil, then 1/2 pint with the new oil... It will get rid of sludge build-up and carbon deposits...

MMO can no way be lumped into the category of slick50 and STP oil treatment... It does not contain PTFE... It has a nearly 100 year history of use in high compression internal combustion engines... Take my recommendation anyway you like, all I can say is that I have had terrific results with the aforementioned cocktail for more than 25 years on both daily drivers and race cars...
