Hey guys is it okay if i use the penrite 10w - 40 racing10 %100 PAO ester Synthetic ? its a non turbo skyline r34 rb25de neo? just confused about these synthethic stuff lol and which is safe to use. semi? full? or pao/ester synthetic? Any advice would be helpful. thanks guys

If anyone has ever experienced this issue an advice would be helpfull i dont want it breaking down on me out of now here lol.

Ijust did that i cleared it 3 times and it came back straight away i also disconnected the battery to see if that would fix it but unfortunately it came back.

Hey guys i have an issue on my r34 skyline with the Rb25de engine. The car has done 94XXX on the clock and its showing the engine light code "21.ignition signal primary". the weird thing about it its that the car runs absolutley normal and it starts normal, i revved up to 5000+rpm and theres no signs of misfire or anything weird. The only thing i remember is that i was travelling at around 60kmph and i pulled the handbrake when i looked into the dash board the engine light appeared. But i dont think thats the issue.... ive been driving it around and probably travelled 300ks with the engine light on. anyone expereinced this problem here? please i need some help and advice. Could it be the following: - Ignition coil and coilpacks are failing? are ignition coil and coilpacks the same thing? - The crank angle sensor? - due to a timing belt and waterpump service? - spark plugs? any advice and help would be great thanks!!
