If I have the synthetic?

also where is the cheapest place for the sparkplugs?

 

ngk coppers are only $1.50 each -- any auto part store

 

mmm...id rather take the stock platinums.

 

coppers are cheaper, spark better and you can change them out like 6 times with the price you pay for platinum.

 

I use the copper plugs but many prefer the platinum. As far as the manual trans, some say Redline, some say Amsoil. I used Amsoil, I like it a lot. It feels much better than standard oil. You'll need 4.5 to 5 quarts. I pulled the reverse switch to drain mine. If you do the same thing be careful with it, it can break, it's plastic. ONLY USE GL-4, NOT GL-5. Several write ups and my research suggest GL-4 ONLY. Amsoil does have it, they call it marine lube or something now but they do still have it.

 

no kidding on the be careful with the reverse switch... I broke mine and had to replace it when trying to drain my tranny.

ouch.

 

Oh, and don't force the switch back in. It has an O-ring on it, make sure it stays in place. When you remove the switch the oil comes out in a hurry. Have a big pan handy. By the way. I think a gallon bucket is all they sell the amsoil in. It's around 30 bucks. Redline may sell quarts, not sure. Ask around about the pros and cons of each brand. If I remember correctly the redline works better in cold weather but the amsoil gives better wear resistance. That's what I read somewhere but you may want to look into it, I may be wrong. I'm sure a good synthetic GL-4 is better than non synthetic.

 

i already have redline from my 60k tuneup, i was just wondering whether you aare supposed to replace it at 120k mile also.

 

Good question, how often is sythetic trans oil supposed to be replaced? Anyone?

 

stock fluids last for about 60K right? I'd assume it can go atleast 60.

ih regular engine oil last 3K and syth can go atleast 6K then I Know tranny fluid isnt the same as engine oil but It should be able to do atleast 100K ?

 

I would change gear oil between 40-60k miles. I use redline and it comes in qts. or gallons.
