It's very safe to use. In fact, you will spend a bit more (if you DIY), however you get many benefits. Better mileage, better protection for your engine (any climate), and smoother (and quieter) running engine. I have used one of the two FREE services that came with my xB2, however, it's sometimes a hustle for me to drive 10 miles and wait for 2-3 hours to get my oil changed.erick182 said:How safe is it to switch to synthetic after 18,000 miles?
It's true you will save a lot of money, plus you know what's going in your car. I am always worried that dealers or independent shops might scratch my car or put dents on my panels.Hellen4Wheels said:I asked the dealer about an oil change with synthetic...a whopping $80...for an oil change for goodness sake. I'll buy my own oil by the case and just take the five quarts with me. That way it will only cost the small amount of labor and the filter.
