New oil out, 75w85 GL-4. A lot of makes are now recommending this weight instead of 75w90 printed in the owner's manual, including Nissan on the Z33/Z34. Redline had been recommending to some to mix MTL and MT-90 so I guess this new oil fits that niche.
Has anyone tried running this oil in a KA/SR/RB20 gearbox yet? I run MT-90 in all my s13s and it's worked well, but there's potenial for smoother shifts with a less vicious oil. If OEMs are recommending the 85w in favor of 90w then the potential wear must not be significant.
Anyone have any experience with Redline MT-85?
