Engine oil Castrol or OEM Mazda
I run Castrol Power 1 in my KTM 350 4T. I'm just past 800 hrs with \~25hr oil changes. It meets the JASO specs my bike requires. I have not changed a clutch ever since I bought it at 280 hrs. I had the motor apart at 500hrs and the Nicasil bore coating was \*perfect\*. That was the last time I swapped out the piston.
5W40 Castrol
I use Castrol Edge. It's cheap and good. I drive a lot and I change oil every 3k miles so 5qt for $25 just fits my life better.
B46 which is essentially a B48 engine. 105000km. Running Castrol Euro Car 5W30 in the summer and 0W30 winter. Live in Canada so the ambient temp can range from -30C to +35C.
Mazda says every 7500 miles for normal duty OCI, and I’ve done every 7500 miles since brand new on my 2014 3z.
It’s now at 187k flawless miles, consumes no oil *at all* (I’ve literally never had to add oil beaten changes, ever, what goes in comes out every time), runs like new, seems easily headed to 250k.
I have used Liqui moly from FCP Euro, lately I have been using Castrol from Walmart.
Castrol Semi-sintético 15w50, relativamente barato, bom pra caralho, não evapora rápido, troco a cada 2500km na minha Biz (experimentando ver como fica aos 3000 neste momento) e tô pensando se vou começar a usar na D250 também.
Conselho de amigo, mete o óleo que a RN recomenda, Castrol 5W-30 Renault com Norma RN 17.
Como dono também de um 1.3 TCe não colocaria outro óleo que não este.
I personally have used the RN17FE 0W-20 (Renault branded Castrol GTX bottles) for 10k km after the innitial oil that was filled in the factory (I don’t know which one was filled in factory). I haven’t noticed any better fuel economy but that can be tough to determine because I drove the car mainly through the winter and did more shorter trips than the original factory first fill oil that I drove with during spring and summer.
Avoid. Tried it, it burnt off very quickly. Back to Castrol with my tail between my legs.
