Gearbox Oil Showdown

[rbee25]

All,

Just want to get a poll on what ppl use in terms of Gearbox Oil.

A poll would be easier to read than the 'Goods on Oils' thread.

cheers

Hands down the best gearbox fluid you can use. It is actually used in forms of motorsport (can the same be said for Redline) and my 193,000km gearbox has ran it since about 110,000kms. I have made over 200rwkws since 150,000kms and do lots of track work, motorkhana etc, last 13,000kms have made between 230-260rwkws,,,all on a std RB20 gearbox which are meant to be weak.

On the other hand there is Redline which i have heard a fair bit of anecdotal evidence that within a few weeks of running it has coincided with gearbox failure

From their own website there are repeated statements of not suiting synchro gears in certain applications, or not suited at all for synchro gearboxes I was going to use it but when there website said not to be used with synchro gearboxes ????

Motul Gear 300, bout $30 a litre. worth every penny!

[Mr. Keets]

I've run Redline in my 32R since I bought it, both engine and g/box approx 12,000K, my R makes 430 RWHP on the original build. I dont do anywhere near as much motorsport as Troy-a few drag meets here and there and the ususal spirtied driving I suppose, but when I changed over I immediately noticed the g/box felt firmer in the shifts and to date my oil pressure is still the same.

Not sure about Redline not recommending g/box oil for synchros but I wrote to Redline and recieved written recommendations, though i'm going to check out the site again though just to be sure.

As for Motorsport, Redline has a long tradition of providing lubricants to many teams in American motorsports. As an example, next time the NHRA fuellers or floppers are on check out who sponsors them. Sure Team Force is Castrol but look at the rest. Having said that, what's on the wing or container isnt always what's in the container - it may for example say Fuchs but it might be Redline

In the end its whatever your comfortable with and what your pocket can afford.

Castrol, Rb20e box behind an rb30det the oil must be doing something right

[BHDave]

lol, you did better than me! I only had an rb20det box hold up behind my rb25 with 280odd rwkw. That thing hung together for over a year before i got around to putting the 25 box in. It's back behind another rb25 now too.

[Ronin 09]

yep castrol syntrax is the business

went from Redline to Syntrax and it is sweeeet

32R with 340rwkw

Alot of my work is dealing (testing) with lubricating oils aswell as base oils. ALMC (Australian Lubricant Manufacturing Company) make all the castrol oils locally and their quality control is far better than than the rest. I'm not sure about Redline & Motul as they are manufactured in different countries, but ALMC make many different oils for various companies including Honda and Castrol and their quality is awsome.

I'm using Redline at the moment in my 32gtr and it is ok.. i haven't used the castrol stuff yet but it's definately next on my list.

Cheers,

P.s i don't work for ALMC

i've used redline lightweight shockproof in my GTR for about 2 years. a fair few track days etc. no problems at all.

redline lightweight shockproof. no probs; nice and smooth.

Castrol VMX-90

Redline Lightweight ShockProof®

A unique gear oil designed to lubricate racing transmissions and transaxles which see serious loads (not recommended for most syncro-type transmissions). It has excellent low-temperature flow which allows easier shifting when cold. May be used to obtain maximum power transfer in racing differentials which do not see high temperatures. Similar to a 75W140 gear oil, but with the lower internal friction of an SAE 30 motor oil.

Used in most road-racing differentials with moderate power and dogring racing transaxles.

after having VMX80 in my GB for a little over a month now, the gears were starting to feel real notchy.. It was great at the start (and made morning whine go away), but after a month felt like sand in my GB.

The other day I put in Redline Shockproof lightweight in, and what a difference!! WOW. although its quite pricey, the GB feels sooo smooth between changes now, cant believe it.

Defn recommended.

[SimonR32]

redline shockproof is the go...

over 300rwhp with a stock rb20 box backing it up for 18months before it broke... and that was belting the hell out of it

gtr now had mid 550rwhp, stock box and redline with no problems *so far touch wood*

[grandmasterb]

I'll be filling mine with Redline again, i tried the Motul but didn't notice any difference and never used Royal Purple.

Stick with what you know i guess...
