Syntrax is good stuff for Scooby boxes. I tried Silkoline full synthetic but got rid of it quick as it promoted crunching from 4th to 5th at changes 4000 and above. Syntrax cured this completely.

Hi All.
I have just discovered that my gearbox syncro to 4th gear is gruncing at high rev gearchange from 3th to 4th.
I have asked the local dealer about castrol syntrax 75-w90 which i have seen You guys recommend when there is a syncro cruncing,but the syntrax is not full syntetetic! it says "syntectic based" on the label and the castrol book recomend a "SNX-S 75-w85 full syntetic".
What do you think i scould try before i rebuild it again???.
It only seem to last 40000km becourse i had the same problem before.

Regards from Denmark.

I don't use it but I also have heard its very good.
Try Shell Gear box oil as I here thats equally as good.

 

Syntrax is very very good, and it is what Castrol recommend.

 

Denmark-I had exactly the same problem with 3rd to 4th and 5th to 4th high speed changes,i put Syntrax in it and it immediately made a difference,after about 1 week the crunching was gone,cant recommend it highly enough,i'd put it in my box any day(car one that is)

 

I use it and I can say that have easier gear changes than before.
Doesn't matter if it is semi synthetic, just change it more often.

Thanks for the info guys.
I have ordered 4ltr. of syntrax so i will change it today to see if it makes a difference.

Thanks.
