link doesnt work

 

It does now... sorry about that

 

I used roral purple on my celica gt-s and some months on my 350Z. it's still a good synthetic...but i use motul now, plus i get it cheaper

 

damn, guess i should switch to mobil 1 instead, good bye RP

 

Good find, interesting read. Hmmmm now to go Mobil 1 or Motul 8100???

 

Apparently mobil 1 is a class III oil now, following castrol, so go Motul 8100, as its a class IV/V full synthetic oil.

I was reading somewhere that referred to BMW's not doing so well with Royal Purple because it doesn't meet BMW specifications.. this article sums it up.

Nice find!

 

My service manager at the dealership tells me to NOT go sync oil..... I forgot the exact reasons he gave, but with 3 oil changes done on my car..... what do I do for the 4th?

 

If your car is brand new, dont go synthetic for the first couple oil changes, after that then go for it.

 

Nonsense, an OWT that just won't go away.

 

motul 300v > motul 8100 > mobil 1.
correct. the reason i no longer use mobil 1.
i waited about 5000 miles to let the engine break in.

 

man everytime there's "purple" involved you know something's f ed up lol

 

Ok... So what is the FINAL choice of the Best Synthetic for this car??? I was a big fan of Mobil 1 when I had my 04' G35.... I'm close to 13k on my G37s now and I'd like to go Synthetic!
