Regular oil changes are essential for maintaining the health of your engine and preventing issues like clogged oil screens in the variable valve timing solenoids. While synthetic oil may offer some benefits over conventional oil, the frequency of oil changes is still more important than the type of oil used. Following the manufacturer's recommended maintenance schedule for your specific vehicle is always the best approach.
Regarding replacement of the variable valve timing solenoids, it's difficult to provide a specific mileage at which they need to be replaced since it can vary depending on a variety of factors. However, if you're experiencing issues with your engine and suspect that the solenoids may be the culprit, it's worth having a qualified mechanic diagnose the problem to determine if replacement is necessary.
The prices you mentioned for replacement solenoids seem high, so it may be worth shopping around for better prices or considering purchasing the parts online. Keep in mind that labor costs for installation will also vary depending on the mechanic and location.
