I just flush brake fluid every year with a break 3 or 4. No high priced is needed.Takes around 1 hour.
I went back to Amsoil after 2 years without. I do not think Mobil is worth the money based on the numbers and contacting Mobils CS (which sucks); if you are doing longer drains which I love and do (and test for). I also have used other fluids in the oil and other oils adds. Most are ok and to me, the CS make or breaks it. So after using Amsoil for 14+ years and LC20 for 2, now back to both. If you are NOT doing longer drains, what do you think a dino cannot do that a syn can? I am getting at, if you are doing normal drains use a grp3 oil and say the money; if normal drains.
Lastly, as I tell every car dealer, "is your car so poorly made that you are pushing the warranty". Then they get the hint
If you are handy get or have some mm tools around and an OBDII & CAN, you are good to go.
