After I changed to Mobil 1, my car started burning oil, about 1 quart per 3000 miles. I was running 10 30, but now I am going back to 5 30, ne1 have any ideas why my car started to burn oil when I switched to synthetic? Because of its thinner structure? If I add an oil cooler will it help it out? I will need one when I go turbo anyway, and it won't hurt anything now so why not? Are the ones in the store nice? Any other suggestions on oil coolers and possible sizes for a 1.8L tib? Thanks for any help.
