A few weeks ago I poured a product called engine restore with csl in my 2002 Max. engine and immediately I had a SES light along with engine misfiring. I took the car to Autozone for a free computer scan and they told me that the camshaft position sensor had been damaged. Since I had an extended warranty, I took it to Nissan stealer and they replaced it at no charge. Then a couple of days later the engine started to sound like it had a couple of bad lifters from oil starvation. I was told that the product that I used had clogged up some of the oil galleries for a few seconds and some of the lifters had been damaged. It was actually cheaper for me to replace the engine (it was not covered by the extended warranty) than to fix mine. I have always used Mobil 1 5W30 and never had any issues with my car until I decided to use that product. My suggestion is to always change the oil at regular intervals and don't use any oil additive since these engine have so many sensors that can be damaged.

 

common knowledge to veterans on here...there is no reason for any additives

 

happend to a buddy of mine use 2 bottles of lucas oil stab and it would not start :| toko him a few days and a couple 100's to get it back to how it was and i agree with sooner none needed

 

i used that stuff in my 97 pontiac grand am with no problem before i knew about the issues.. for some reason, i never wanted to put it in my max though.. after reading through a few recent threads, im glad i didnt

 

It actually works well in older, cam in block engines but that's about it.

 

Doesn't our manual specifically say not to use any additives...?

 

yeh but how many read their manuals

 

sure does...but if people actually read them, we wouldnt get 20% of the new threads...

 

wow I was going to put some lucas oil stabilizer in my car, thanks to this thread I wont.

 

uh oh lol. i put in lucas oil stabilizer in mine...i guess i wont be adding it anymore to my oil changes. btw i have no manual

I think the problem with the cam position sensor was a coincidence. There was a TSB or recall for that quite awhile ago.

I agree with the rest....no additives needed.

 

Is Restore even safe for synthetic oils? I think it's a dino derivitive, which would be a no-no while you have synthetic in the crankcase?

 

I've seen "mechanic in a bottle" trash engines in older cars too.

Agreed. Most cars last a long time if you don't fiddle with them. Old Honda's, Toyota's and Datsun's were able to establish a good reliability reputation LONG without mechanic in a bottle or synth oils. Of course, "mechanic in a bottle" has been around since the early days, but my point is regular ol' dino lube and basic maintenance per factory specs will keep a car running for a very long time.
Most of us either don't keep a new(er) car long enough or we have cars that are already very old before we acquire them, so there is no real reason to seek out the perfect "mechanic in a bottle".
