The Goods On Oils

[barry1024]

Can someone learn me on penrite oils?

Enviro+ fully synthetic, or SIN 5 or 10 any good??

i feel SIN0 have more low end response than motul 81xx

i just put castrol edge sports 0w 40 will that be ok i new the rb25 engines

it will be ok but there are better oils for next time, read the thread for examples.

[Trozzle]

5.5L of Nulon 10w40 fully synth shit went in. ~4L comes out. After 4000km. What shit. Last oil I used was 8100 5w40, and the entire 5L came back out when I dropped it. This oil breaks down and burns very easily, won't be using it again after I get through what I put back in (like I said previously, got 10L cheap so couldn't turn it down). It also stank a bit more than it should.

Will be keen to try out the 8100 10w40 stuff next.

too thin... if you want to use castrol edge in an RB go the 10w60

wow that's an awful lot to burn and you definitely don't normally burn oil?

Definitely not. Never noticed it out the exhaust (on or off boost), have fark all blowby (absolutely nothing came out of the catch can) and as I said with the previous oil drop, the whole 5L came out whereas this one was a lot less

Might honestly just be the oil, which wouldn't bother me too much. Would rather the oil be ghey than have bigger problems.

Been using Nulon 10W-40 since I bought the car 2 years ago with no probs....serviced roughly every 5000km +/- few hundred Ks.

However, I recently switched to Motul X-Max 10W-40 cos its only like $7 extra from Autobarn (for 5 litres) compared to the Nulon (6 litres worth).

I haven't noticed any difference apart from peace of mind knowing that the stuff in the car is "a quality brand" and is guaranteed to be 100% synthetic POA/ester based

[Birds]

There's an X-MAX 10w40?

[pipster11]

holy degrease batman, put some of the $15 gulf western into my new corolla daily

i haven't even put 2 tanks through it and its gone black

i'm pretty impressed with it, i've been wanting a car of my own to try it on for ages

haha, I'm hoping that might have been why my shithouse Nulon went black after 4000km - did a better cleaning job than 8100.

Sadly, I think I'm wrong.

So this $15 GW business, might do my noisy lifter some favours if I could be arsed changing the oil twice in a fortnight

[me_larr]

Yes...there's an X-Max 8100 10W-40. Its only $70 from the ricebarn too. Recent release by Motul I think....

i think all the gw oils are good at degreasing is what i was trying to say

i'd go the synx 3000 for a skyline (20w50 is too thick for me)

[AngryRB]

Hey Guys,

So what do you think about Mobil 1 Gold??? I tried castrol edge, and dropped it after a few hundred k's cause the car felt sluggish, as soon as the Mobil went in the car started sweetly and the difference seems obvious, event the turbo sounded more crisp...

Stays the same clear gold right upto the next oil change and never goes down on the stick...Does this mean its a good oil or are my oil rings just sealing off really well??

[xALmoN]

detergents aren't working if the oil doesn't come out black right?

[Trozzle]

detergents aren't working if the oil doesn't come out black right?

yes and no. Black oil doesn't always mean detergents are working....can also mean burnt oil. I'd also say that just because the oil comes out a bit lighter colour, doesn't necessarily mean that detergents aren't working. Might just mean it was nice n clean inside and you didn't get the oil hot enough to gunk up any further.

[Birds]

That's correct, there are a lot of ways to read the colour of an oil. Logic needs to be applied.

A guy I used to know put some oil in his car before getting dyno tuned...his tuner checked the oil afterwards, found it was black and incorrectly assumed it was a shitty oil. Couple of problems here:

- Dyno tuning and other intensive engine work (racetracks etc.) can burn an oil no matter how good it is. This is important to keep track of, as extreme driving behaviour can shorten appropriate service intervals in street cars.

- Previous oil may not have had as much detergent in it, leaving plenty of build up for the new oil to drain out.

[Galois]

detergents aren't working if the oil doesn't come out black right?

As the other's said, if after 5-10k the oil comes out golden it has lasted well but not cleaned the engine at all, if it comes out black it has either broken down, cleaned well, or both (I'd guess usually both). You can gt some idea by smell bit it's a bit subjective, though you do know if it smells burnt to all hell it's broken down badly.

You still using sougi birds? What will be your choice when your stockpile runs out? I'd be looking towards xcess or xmax. Is that synx 3000 stuff detergent heavy? Maybe that's the cheaper way to go these days.

[Birds]

Yeah I'm still on Sougi...I have a personal stash leftover, but I'll probably make the switch to Syn-X after that...only because I can use it in my car for free haha. I have thousands of litres of it. But it is a decent oil nonetheless. If I wasn't a distributor I'd probably consider Motul too.

I've got this too but in a forged engine, seems good so far.

[ARTZ]

for best all round performance on the street 8100 xcess is the shit imo.. I use 5-40,

Mobil one or gold is decent enough too so is penrite syn.

I didnt like castrol

Burnt oil will be black and thin/runny, if your oil drains out fast it is probably burnt or just not good oil..Good oil should be darker than when you put it in of course, but it shouldn't be black unless your engine is tired and it should drain slow towards the end.

i want to know has anyone tried Fuchs oils and what are they like, can get 20l drums of full synthetic for about 150$ just want to use it in my work ute mainly
