To Nulon Or Not To Nulon?

[sark021]

Thanks all for the continued feedback. I've decided to Nulon (E30 engine treatment) based on my previous experience and your feedback as I know your rides are as precious as mine and wouldn't want to do the wrong thing. This is despite all the negative stories I've read on the net regarding oil additives.

Now..as a bit of a side issue....

I have gone to the Castrol site and used thier ready reckoner where you start typing in your vehicle and select your model from the drop down list and then it recommend the most appropriate oil for your car. For mine it came up Magnatech. Now when I did this same sort of thing on the Nulon site, the function (drop down menu..the list of vehicles in order etc. etc.) was suspiciously the same. Can I suspect that there is an alliance of sorts between Castrol and Nulon or do you think that Castrol actually owns all or part of Nulon. Maybe they share the same web developer. This could, say, give Nulon a bit of credibility if associated with Castrol.

Also as Castrol's site came up with Magnatech as the recommended oil and Magnatech has that fancy stuff that "clings" to the engine (ala Nulon), is there some sort of synergy going on here.

Just a thought.

Nulon's 100% Australian. Nothing to do with Castrol or anyone else.

I tried the Nulon 10w 40 and changed back to Motul after 2 weeks. The Nulon is probably good for the price, but the Motul 10w 60 runs the engine much smoother and quieter with better oil pressure, but it cost 3 times the price of Nulon.

Comparing brands using two different viscosities is a flawed exercise at best. Any -60 oil is gonna give you higher pressure, nevermind the French stuff. It is 50% thicker at operating temp than the engine spec calls for after all. Personally, I'd only be using a -60 weight oil in a motor with billet oil pump gears as you're asking a fair bit more of the oil delivery system if giving it some stick. Cruising would be ok.

This thing with additives..........manufacturers have been saying for years not to add additives.

I note that when our cars were having diff issues with the diff centres being built "too tight" that Ford's recommendation (via service bulletin) was to then add 100ml of Lubrizol to the diff to try and fix it........so much for them saying for years not to add "additives".

For warranty purposes, I can understand why they don't want us ordinary public (who me?) to do it but that doesn't mean they don't work. If at least quality additives don't work, why do oil manufacturers add many compounds to their base oil product?

I have never had an engine failure running Nulon even when I boosted my 250 alloy head crossflow to 28lb boost (once only and then chickened out adding any more).

Also beware of running full synthetic in a road car that is not being driven hard. Racing yes, ordinary use no. Full synthetic is not recommended by the motorcycle shops that I visit as in normal road use it will glaze the bores and start using oil (and they make 180hp/litre). They recommend semi synthetic as a better choice.

Just my 10 cents.

My diff has recently started that fantastic BA whine, mechanic almost missed it, but took it for a long drive and caught on to the sound, and he wacked in nulon also - whine is starting to muffle a bit, but apparently it will never go away. Just my little bit, and my mechanic also has a BA too, so I guess whatever is good for his own car is good for mine.

For good or bad...

I finally put the E30 in yesterday and I can already feel and hear a difference. I'm sure it's not just a placebo effect as you do get to know after a while what your ride sounds and feels like. So I'm sure I'm already feeling the benefits. Go Nulon.

Bye the way...I read that the ZF 6 speed transmission is a sealed unit and you can't top it up with something like Nulon Auto Tranny additive. If I'm wrong...can someone tell me where can I pour it into the transmission fluid!!!

I believe you need to replace the pan and filter mate, its not just a top up job, you also have to add the oil at the correct temps - good idea to get a workshop to do it.

Newbies first comment on forum.

Hey SavageF6, Motormate on South Road sell the full range of Nulon Syn Diff/Trany oils.

Will be trying the Diff oil myself soon, as well.

I have always used Nulon 15w/50 full synthetic oil.

[Dream Machines]

So far I've never used nulon, mostly motul (600 C dot 5.1 brake fluid), Redline (water wetter, SI 1) and Fuchs 10 W 40 fully synthetic

the car has definately improved alot since putting those fluids in

To stop the whine in my Tickford AU XR, I put redline 85W250 heavy shockproof diff oil in the car

might cause drag and lower accelleration pickup but it worked
