Yes, with most organics you are going to get some ashing, that is a fact. Yes, some organics do have no ashing but rather burn to release only water and carbon dioxide.
Yes, its NOT going to be a "normal" organic if it survives higher than 1112 degrees Fahrenheit Its probably going to be some metal or semi-metal complex to survive at that high of a temp. Can you seriously name any? Anyway, zinc is probably a component of your ash and RP will have more ZDDP than any "SM" oil, regardless of synthetic or conventional. Personally, I was considering Royal Purple at one point until I discovered the ZDDP issue. Considering that our Cats will see significantly more oil than a normal piston engine, the effect of the cat poisoning is magnified. |
Cat poisoning is bad mmkay
http://tonova.typepad.com/thesuddenc...runk_cat_2.jpg On a serious note, burn more oil! Want to see the differences (Mobil1?), and you already have the setup... |
I'm requesting Castrol GTX 5w20, not because I could hope to gain anything but a good read from this information [I'm ignorant], but because it would apply to a ton of people on this forum.

http://www.autosafety.org/article.php?scid=151&did=963 http://www.autosafety.org/uploads/ph...WOilSludge.pdf Guess what they are REQUIRING them to run now? 100% synthetic. Next you're going to tell me it's not applicable since those are piston cars - not true. Their issues are based on oil change interval and heat issues. Our car has more heat than most. Sludge is an issue in rotary engines too. As has been said already, burning up the oil in this test just shows how much material can be burned up at 1000 degrees. It doesn't show lubrication properties, or even come close to the amount of heat in the engine to prove anything. In fact, it just shows that royal purple contains more additives that prevent sludge, corrosion, and wear on your engine. First bite, it will be a long day. If Mazda says no, and Mazsport says no. Then I'm going to say no. |

This data, while interesting in a curious sort of way, tells us nothing about oil as it is used in an internal combustion engine, regardless of type. BTW - Mazda only says no here and in Oz - it is OK everywhere else. They also insist on 5w-20 which we also know is a horrendous mistake meant to appease the EPA and meet minimum warranty requirements, not engine longevity, so Mazda's recommendation (Mazda, having been well established, know the least about the Rotary motor, despite being the manufacturer) is of little value to the discussion. |

Bite two, I'll take the manufactures word and a well established tuners shop word over tom, dick and harry from a message board. However, If one of the "leet" synthetic people can show me hard data and a large cross section of cars that have not had any issues and have been running for 70k miles I'll change my tune. Once again, taking the word from some people on a messageboard is to much risk in my book. |
Then don't bother.
But at least get a basic understanding of the rules of logic. |

Didn't you get the memo? We are putting new cover sheets on the TPS reports.
I can send you a copy of the memo if you don't have it... |

Please attach a copy of the missing memo to the weenus reports.
Please burn more oil. I am curious. Maybe something useful will come of it. |
This test is a test, but... car engines do not burn oil. Period. While the flame temperature is high, the residence times are too short for oils to vaporize and burn (I posted before, to links to basic physics, why liquids do not burn, do a google if still confused). The sludge you obtained is indeed inorganic - it would not stay long in there, gasoline is a good solvent and it will wash it into the catalyst.
What your study showed it that the catalyst is in danger with that oil. Fact known and the reason why their oil is not SM qualified (nothing to do with convenience - is not all that hard to qualify an oil when you are as big as RP). So now the real question is: if your cat fails out of warranty and Mazda finds out you used non-qualified oil, who shells $500 for a new one? Your guess as good as mine... Engine is fine with either oil and before people open high mileage engines that ran on certain oils and post pics of the ports/deposits, we really have just theory to debate to death. Someone claimed earlier that Mazda insists on 5W-30 oils - they don't. In US, they insist on 5W-20. I disagree: 5W-30 for 3 seasons and 10W-40 for summer is just about right for where I live. I like cheap Valvoline Durablend also - nothing against synthetic, I am not convinced its advantages when changed every 3000 miles are worth the high price. And on our cars, running more than 5000 miles on any oil is risky - too much gas gets into it and breaks its viscosity, dino or synthetic no difference. |
does the rotary burn a little oil since it in injected into the engine?
I have a little over 40K on RP. usually 5w/30. Live in Ga and it gets hot. I use 10W/40 on my summer track days. I do know that engine temps are cooler with RP vs Dino. I do know that RP will free up a couple of hp. I dont know if it is really a lot better for the renasis---but I am convinced it does hurt the engine. It is expensive:) olddragger |

Great stuff staticlag, thanks for taking that on. I'll second (or however many it makes) that I would like to see a synthetic like Mobil 1 or Amsoil tested. They're both closer to a "virgin" state of synthetic stock. It's my understanding that at about 450° synthetics break down into the esthers they were made from so it would be interesting to see how much ash they leave behind.
So far I've only used Castrol dino juice in mine. Probably all I will use. It works just fine so far. |

Your analogies suck. (People said Synthetic oil is a waste of money) I like Organic food because it has been proven that its better (I like Synthetic Oil because it has been proven that its better) Thats how I see it. each of their own. :spank: Next ~~~~

When the new renesis engine came out many tuners were saying that the Apex seals couldn't handle FI. Now there are FI kits available for the 8, more kits are likely to follow after Cobb realeases its acces port. I have yet to see any rotary engines fail because of synthetic oil. This debate will go on forever so it really just comes down to what people want in their engines.

Yes, I plan to test more oils, such as castrol and mobile1. Though I will stick with the 10w30 variety so I can compare them to the results I already have.
I will however run a 5w20 sample of whatever brand you guys use the most along with its 10w30 variety so I can compare across viscosities. Thinking more about the test, I have also realized, that the real temperature is not only 1112 Farenheit, but also the flash temperature of the burning of the oil, that itself should be pretty comparable to the peak flash temperatures experienced during combustion. .61 grams is about .75-1mL in the crucible, or about the size of a silver dollar (the old kind, not the new ones) if it was placed on a flat surface. Its kind of suprising to see the 7inch flame that comes off of it, it burns for nearly three and a half minutes initially. |
