Engine oil IDEMITSU or Lucas
Idemitsu 05-W30 from Unioil kasi I cant find Castrol for my Mazda
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.
Regarding brands, if you want to stick with factory oil without dealer price, Idemitsu is the brand to get. I emailed Mazda corporate and they said Idemitsu is the OEM for their oil.
I have a Sohn kit and run Idemitsu engine oil in the engine and Idemitsu premix in the Sohn. Runs lovely and smooth and the original cat is still doing the job.
We use Idemitsu for engine oil and transmission and red line for front and rear diff. Red line makes a good fluid for the transmission also.
I paid $67 for 4 qts of lucas full synthetic oil and a filter on Amazon and just grabbed an O ring from harley. Harley's oil is fucking garbage. Lucas, Amsoil, Motul & Mobil 1 full synthetic are all damn fine products.
I used lucas in my honda and will use it on my next change for harley
Personally I run Lucas oil in mine, not just my current zzr600, but even my older vintage bikes when I had them. It isn’t crazy expensive and is high quality.
That looks like you dropped a valve. Yes Lucy’s oil will help. It will lubricate the chamber so you can take out all the pieces.
I installed an oil cooler on my buddy's 370z and he dumped in oil and a full bottle of this and I just scratched my head
