Golden Spectro 4 Semi Synthetic ???

11 posts in this topic

Has anyone tried this oil out? I have been a fan of Amsoil 10w40, however Cycle Gear near my house recomeded this out (they don't sell Amsoil). I only ask because my freind ride's a KX 450 and his clutch was making a winding sound comming back to the pits and he said he uses this oil as well.

Used it for the first 60 hours on my 426. the 20w-50 in the summer and 10w-40 in the fall. Didn't cause any problems for my clutch.

Golden Spectro 4 Synthetic Blend is a good oil that performs well, and more importantly, holds up well. I used to use it before switching to Mobil 1 Racing 4T, and then Amsoil.

Your friend's clutch is not making a whining noise, his primary gears are, and it's no big deal, more than likely.

Gray, one quick question. I was on Amsoils web page just a bit ago and they said they are fine for wet clutches. I know that you had to hear that the boys at MXA said not to use it(read that some time back). That's kind of why I said I would give this one a try as well. Do you think a fully synthetic shortens the clutch life from our beloved dirt scooters?

I ran the same clutch in a 4 speed YZ450 gear two teeth taller than stock for 3 years on Mobil 1 and Amsoil, and it was still in perfect condition at the end of that time. I don't know where the statement from MXA on this subject came from, but it's patently ridiculous, and has no basis in fact at all.

visual comparision.. i wish i could of done some kind of test for sure tho..

the oil if i rember correctly, was foamy, a bit milky and plan out had alot of silver flakes in it.. switched to amsoil.. nothing since.. and i change it every 2 rides depending on how hard.. sometimes 3... it just didnt make me feel safe...

Visual clues to an oil's condition are almost entirely unreliable. You can see if there's a bunch of stuff in it, and coolant contamination is pretty obvious, but there's not much else you can tell about it, even by the color.

I do agree with you that Amsoil is better, though.

and that is also another main reason im using amsoil. i feel so much more confident in that my motor is not gunna blow, or that im wearing parts out faster inside the motor.. due to a lesser oil..
