Agreed![/quote] Somebody finally agrees with me. :o |
Yeah synthetic is good until you clog the omp and lines and injectors with it. That's what I hear though. I'm unsure if that is a proven fact. Good luck, I hope it doesn't cost you an engine. I think I'll stay with my Valvoline 20w-50.

Seeing as how the OMP injects oil from probably the coolest part of the engine, I can't see how it would get clogged. (I think the only way oil gets clumpy is when it burns) Now, I do understand that some people argue that it may leave deposits on the rotor faces, as it doesnt "burn" as well as dino oil... However, synth has supposedly come a long way, and in some cases, may burn off even better than dino... I guess we'll see! Car still runs as of now! |
Oops... Ace already said that.... Not trying to steal credit... https://www.nopistons.com/forums/pub...IR#>/blink.png

Hey like I said that's what I've been told. from what I've because it doesn't burn so well it tends to turn into a gel like substance. When this happens it will leave clumps of the jellied substance in the omp lines when the car is turned off. Then because of the cool down process it will harden and clog the lines. But like I said this is just what I've been told. Sorry in advance if I'm wrong. Just be careful and do your research(not saying you haven't) first.

P.S. Still running good. 4 days now I think! |
Ya, its true most of the top tuners use synthetic oil, in their race cars... syn breaks in faster, is less weight, and more vicous, but a race motor isn't meant to truly last that long...
It might be good for a while, but i'll stick with the "dino" oil, its been recommended by too many people not to use synthetic, i'll just go with what works... let me know if problems do arise.. https://www.nopistons.com/forums/pub...IR#>/wacko.png |
I know this debate is ongoing, so a few months ago I asked Mobil and here is the response I got.

In the past if you asked them, they would just say the Mazda does not recomend synthetic oil. Now they have a new blend of oil (Super-SYN), they say it is OK. I have now been using 10w-30 Mobil 1 since July 1st. I have noticed cooler oil temps, smoother idle, and more power compared to the Castrol 20w-50 I had been using with no bad side effects. |
