QUESTIONS

AE86
This might be a stupid question but.....
G70 gearbox/diff treatment - is there any benefits to using more than the recommended amount in my gearbox? Or will it cause damage?
I really like the stuff and definitely think I notice the difference in feel after using it.

There is no substantial benefit in using more G70. The recommended quantity of G70 treatment is to ensure the gear oil in the gearbox is not diluted and the existing gear oil?s physical properties are not altered or changed.


ANTILAG
Ok then.
Long story short, i installed an r33 gearbox into my r34 which was working perfectly fine in the car it came out of but once it was installed into my car with brand new VMX80 gear oil it was crunching 2nd gear almost every time i shifted into it and the rest of the gears were kinda notchy. This was mostly wen it was cold, once it warmed up it was fine.
So i went back to the shop i buy most of my parts/fluids from and i asked for their advice in regard to the problem. More suitable weight box oil etc.
Long and behold they told me to squeeze in some NULON easy shift additive as a cheaper fix. So i did that and it actually made the gearbox alot worse, 3rd gear started to crunch aswell and no matter what temp it was, 2nd gear would be crunchy.
So i raged and drained that oil, listened to my old man and put in some valvoline supersynth 75w90 and problem fixed, cold AND hot.
Hmmm...... product didnt work for me.. why?

Nissan recommend an API GL-4 specification gear oil for theses gearboxes. The use of a GL-5 specification oil (Valvoline Super Syn 75W-90) is not recommended as it will affect the synchros? over a period on time. The working of a Synchromesh is affected by the viscosity of the oil. Notchy gear changes are more noticeable on start up when the gear oil is cold and reduces when the gear oil is warmed up. This is much more evident during the winter period as with the very low ambient temperature. Theoretically using a heavy SAE 90 (75W-90) would make the gear change problem worse during colder periods.
G70 Gearbox and Diff Treatment is a blend of PTFE and friction reducing additives which help with gear change issues.A notchy or crunching 2nd gear is common in most imported vehicle as the 2nd and 3 rd gear synchro is the most used and abused gears. Using Synthetic GL-4 gear oil (75W-85) plus G70 can reduce these types of issue but if the synchro is worn it will not eliminate or fix gear shift issues.

AUSROTARY
Ive been a user of penrite for many years and very happy with it, but where i get my stuff for services stopped selling it due to drama's with suppier etc and now stock NULON oils...... never knew they did oil just thought it was aditives (aparently 2 years ago they started making oil...... and yes its made in Australia also)

anyways the reason to my post is i can tell straight away if an oil is inferior by the way the car drives (its a VT bombidore) so ive put the NULON in and gave it a run and yes im VERY happy with the performance of it and not only that its about $10-15 cheeper than the penrite plus it has the NULON additives already in the oil aswell.

havent tried it in my Rotor yet but as soon as thats on the road NULON is what ill be using!!!!!

We at Nulon thank you for your positive feedback.

With reference to Rotary, please be aware Mazda do not recommend the use of synthetic engine oils in their Rotary engines. There is lots of information on this subject which make for very interesting reading.

They definitely do not damage engine components, Nulon are about performance and protection! But will pass your concerns onto the Technical support team for a greater understanding of the product.

Nulon Pro-Strength Octane Booster does not affect or damage valves and/or seals. These types of products are design to increase the octane level and boost performance.

Thanks
Thanks, thats a great question. Will pass this onto Nulon Technical support team and look forward to hearing what they have to say!

There are a series of tests that are conducted. These are controlled test and test method outlined by the American Society of Testing and Materials and OEM?s. There is hundreds and thousands of hours of testing conducted but a brief outline is as follows. Tests are conducted on different types of engine, manufacturers, model and engine capacities. The final out come is to measure the cleanliness of injectors and deposits. These are described as Intake Valve Deposits (IVD) and Petrol Fuel Injector (PFI) keep clean test, Intake Valve Deposits (IVD) and Petrol Fuel Injector (PFI) cleanup test and Chamber Deposit Cleanup (CCD) both keep clean and cleanup. In a summary how well the products cleans and how well it keeps cleaning.
