Engine Flush and brake flush?
It's your money and time to spend if it makes you feel more comfortable with your maintenance but making a general recommendation for others to avoid the advances in technology is not particularly helpful. And to get to the real heart of the matter... the color of the oil has very little to do with its effectiveness as a lubricant or cleaning agent. Thousands of tests have proven that.
Switch to a quality brake fluid with high boiling points. Pentosin, Brembo, ATE, etc. Skip that generic brand stuff.
Buy quality products, get longer service intervals and longevity from your car.
My wife's 06 Altima has over 100k worth of Mobil1 EL oil changes (annually for at least 6 years) with no issues.
The 3000 mile oil change is very old thinking that keeps getting passed down, all while the oil companies are more than happy to oblige. It's just marketing. Look at Mercedes and BMW oil change intervals. All very high.
