Hi guys, I own a 2010 Hyundai Genesis Coupe 2.0t with 22,500 mi and in excellent condition. When purchased from the dealer had around 18k mi. Just yesterday I got an oil change using Mobil 1 5w-20 synthetic. I have since been reading about the benefits of adding Chevron Techron to the gas tank in order to keep fuel injectors etc clean and free of gunk. While I don't suspect my engine parts to be ridiculously dirty I am still curious to try this product as the majority of the reviews have been very good in terms of small performance increases and improved mpgs. However the prevailing usage theory seems to be that this product should be added to the gas tank *before* an oil change as adding it after can lead to the "gunk" somehow potentially mixing in with the new oil. Can anyone tell me if there is any truth to this theory or can I go ahead and add it despite having just changed the oil? Thanks!
