These guys don't know what they are talking about. First of all, you have mixed synthetic with regular oil. The polarity of the long chain amino acids in the EP (that's what makes the seals swell up) being only a small portion of the overall mix will in effect pull the regular oil away from the aluminum metals (aluminum having magnetic properties) in your engine and cause it to volatize and in turn clog the front chamber of your catalytic converter. Sometimes, these guys try and pull people's legs because they are trying to be cute. That's one thing you have to aware of on this forum. Most everybody is full of lube. But you can trust me. I would drain the oil. Do not drive in anymore. Drain the oil. Remove the oil filter. Get some nonethanol gasoline, kerosene, and marvel mystery oil. Mix 1/3 of each in a gallon jug and a 1/2 gal jug. Fill a new oil filter with Kreen and carefully reinstall trying not to spill any. Replace drain plug and torque to proper specs. Start the engine and set idle at 2500 rpms. SLowly add the 1/3, 1/3, 1/3 mix. It may idle rough and make some knocking noises at first but that is just those long chain amino acids not wanting to release from the aluminum parts in your engine. You will probably get a check engine light but no worries. Just unhook your battery and it will go away immediately. Run the mix for approx 35-45 miles with max rpm never above 6000, drain and refill with new oil and new filter. Please keep us posted. Some followup pics would me be nice. FYI, I have not been drinking or using non prescribed drugs.
