I ask because of this quote from a Motorcraft engineer when interviewed about their 5w20 blend oil: "Never add other aftermarket additives to MC oil. Much care is put into formulating engine oils. Many of the aftermarket additives upset the balance of our fully formulated oils and can actually degrade our oil's performance". He then goes on to more specific examples and why this can happen. I have to assume nearly every oil manufacturer would tell you the same thing to not add anything to their product.
It makes sense I suppose. Yet people here rave about products like LC which has a proven track record and years of "experience" with many kinds of vehicles. But have they been newer cars? I have a 2006 Honda and bought some LC (and FP60) because of the good reviews. Now I am wondering if products such as LC20 were most useful for older engines and the poorer quality oil, such as seen even 10 years ago.
Today's high tech engines and much improved oils may not need additives and might, as the engineer stated, actually degrade the ability of the oil to do its job. In fact, my Honda manual says engine damage might occur if you use oil additives and for that reason alone I might wait until after warranty to even try such products. What do you all think?
