Engine oil Castrol or IDEMITSU

Idemitsu 05-W30 from Unioil kasi I cant find Castrol for my Mazda

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.

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.

Have been using Motul 5w30, But I recently switched to Castrol edge 5w30 as it's easier to get quickly and has always ran well in all of my turbo direct injection cars.

Last change oil ko 5700km di naman sumabog swabe parin manakbo

Oil used was Castrol's Power 1 5w-40

Idemitsu is responsible for the oil that powered the Mazda 787b; they know the rotary like no other. I exclusively use their synthetic 20w50 and premix.

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.

Castrol sucks
