Am I Losing My Mind?

[mattyb]

Where do I start...

I used to run penrite oil in the 'T' before it blew up, now I have the FG F6 short motor in it and it's done roughly 10000k's.

We ran it in on Castrol Magnetic for the first 1000k's, changed the oil and filter, and I was putting off changing the oil untill now as this week I'm off travelling roughly 1500k's in a weekend, and next week I'm heading down to Hervey bay where I'll be getting a tranny service done, and the centre diff bush replaced along with a couple of other little niggling things, all up it will be about a 2500k round trip.

So, I bought some Nulon 10w40 and a new filter, did my usual 45min service and checked that everything under the car was sweet before the trip, and upon start up the car seemed quiter, yeah oil can do that. Then, I shifted into 'D' and no noise at all from the tranny, went for a drive and the car seemed a LOT quieter to the extent that I could swear even the exhaust note at 60kph was quieter. Put my foot down and brought it into boost, and the turbo seemed to sound nicer too...

Anyhow, I picked up the missus, and she notice that the transmission didn't 'clunk' like it always does, and when we were driving se said "the car sounds quieter today, what have you done to it now". As if to imply that I spent more money on it without her knowledge.

I haven't smoked any hooter, I've not been drinking for the past 6 days, and I haven't bumped my head recently (to my knowledge). Can an oil and filter change really do this, or have all our little problems somehow been realted to using a cheaper oil?

short answer Yes

oils aint oils

some people don't like nulon but I don't know why every engine I have changed over to it runs nicer.

my new (second hand) one will be getting done straight away tomorrow when I pick it up also will get the 80,000k engine treatment from nulon before boost gets wound up.

although not drinking for 6 days can do funny things to you lol

I love Nulon as it has AAT which is like Teflon. It will coat the internals in it and make it very slippery.

It can make a motor quiter and rev better. I used it in my boat last year, had a 40hp diesel that was about 15 years old.

After using the Nulon oil in it, I gained 500rpm that was not there before and it was also noticably quiter and reved faster.

cheers, guys. Still dumbfound as to the improvements, wishin I had done this earlier. I'm a Nulon lad for good now.

ive heard bad things about nulon from a few mechanics as after its used up it clumps together and doesnt feel good at all at drain time in comparison to any other type of oil ..........but it could all be bullsh*t

[our06t]

I've never run it more than 7500kms but it comes out like any other oil even after a good cooking from the turbo

Yep, same here. Usually by a bloke wearing an opposition branded uniform from his workshop plastered with opposition branded banners thinking about how much more he could be making out of you by selling his preferred oil.

Never had a problem with Nulon, brilliant stuff. After a long trip when I turn off the motor I can hardly hear the turbo spin down. All those other mechanics who say its crap are only trying to sell you something else.
