Maybe this has been re-hashed a lot, but I have been searching past threads (a lot, back to 2002/2003) and I don't know if this has been covered.
Mobil 1 (the common variety that is found at Costco for $30 a case), touts itself as 100% synthetic, which I thought was a good thing. I have read that just because an oil SAYS it is 100% doesn't mean it IS 100%. There is an additive package that needs a vehicle to carry it, and that vehicle is dino oil. The percentage of dino being as high as 20% has been mentioned. It has also been said that if you read the label it says 100% synthetic base stock, exclusive of additives. I think this has been removed from the label since then. Now the "new, improved" Mobil 1 has twice as much synthetic as before. How can you get twice as much, if you already had 100%? I also read somewhere that if a product is 51% "something", you can call it "100%" or "fully" of that "something".
I started searching for synthetic oils on the web, and found two major companies, Redline, and Royal Purple. Both seemed about the same, but I came down on the Redline side, if, for no other reason, they are a local company (S.F. Bay Area). I am partial to Chevron, too, as I have heard they are the one oil company that puts the most into R&D. No one does more research than Chevron, I have been told. I was disappointed that I could not find a Chevron synthetic oil on the market.
I ordered 3 gals from a mail-order high performance supplier (starts with J) and when I got the bottles, saw no API logo on the side, just a statement that the oil is "Recommended for API SM/SL/SJ/SH/SG/CF" . Now I'm worried..... I happened to be in Benicia one day, so I stopped in and asked a few questions. The rep said that to get API certified would increase the cost (as stated in the AMSOIL link), and they would have to LOWER the performance of their oil to meet the standard. I presume that means less ZDDP, and phosporus (maybe), to avoid cat contamination. I also asked about cleaning, and would I have to run a flush to prevent and deposits from getting knocked loose, he said no. Another question was the additive package, did they use a petroleum-based carrier oil? He said they are such a small operation, they put the additives in during the refining process, no carrier needed.
Mobil 1 has gone up in price at Costco lately, it was around $26.50 per case (6 qt), now it's at $30.00. I got the Redline for $29.99 in 1 gallon jugs. So for the added price of $1.50 a qt., am I really getting 100% synthetic base stock oil, with all the high-performance additives? Can I safely go a 10K OCI without fear? I did flush out the old dino oil by running one quart in the crankcase for about 1/2 hour, so any residual is gone. New filters both times.
Any comments? Is the M1 really not all it's advertised? Is the Redline really that good? Thanks in advance, and I apologize if this has been covered in a previous thread, and I missed it.
