Also, in the owner's manual, it says the oil additives are not recommanded.

 

Sent a sample of my last oil (Mobil1, K+N oil filter) that had 7,500 miles on it to Blackstone, they said I can easily go 8,500 on the next change. I don't see 10,000 miles on synthetic oil being a problem for me, but I drive 100 mostly highway miles each day. YMMV

 

The 7.500 is just a contract obligation between you and Nissan.
You don't want them to have a legal excuse to terminate their end because of something you did or didn't do!

Especially important for those that buy the extended service contract to 100k.

 

I found the following information useful exposing the truth behind oil additives.

The only time an additive might be used is to fixup/modify a sythetic oil that might be low on Zinc. Zinc has been reduced in modern oils due to the propensity to degrade cats after long use [After 100k].

The steps necessary to maintain as near new performance on a 300,000 mile engine are very different from most owners who sell ~~ 60,000 miles.

The 2nd and 3rd or 4th owners might thank you for your diligence.

 

i think he meant 9k km

 

slick50 has been sued and paid out 20million dollars to their customers...

I find it very frustrating that consumer reports and other websites claim additives do not work, when there are hundred thousand dollar independent studies showing their benefit.

Check out the article I posted above before purchasing any oil additive, because it is true that many have false claims giving the good ones a bad reputation.

slick50 being one of them...

Lucas oil is suppose to be good?

 

No. Their additives have a cool little gear display in Pep Boys and Advance Auto, etc.. that when you turn the wheel, the oil sticks to the gears and lubricates them all better than regular oil. It's kind of cool to watch, and if our engines were made of plastic gears and turned that slow, it might be good. But, at any rom, their additive oxiginates the oil and causes it to froth up. The issue with oxiginating, is that it increases the acid build-up of an oil and this breaks down the base stock and causes sludge. Do not use.

Good demo of what I'm talking about:
