Hi all,

I'm a bit uncertain of the time period that the current oil has been in the TJ we just purchased. Needless to say I want that oil out asap; but I'd like to flush out any sludge etc, before I go and put some nice and somewhat expensive synthetic oil in there.

Is there any risk in using the Wynns? I've read their Product PDF and it said that there can be sludge buildup on the oil pickup - necessitating oilpan removal?? Not excited about that option!

Steve

You should be fine, one thing people like to complain about after using flush is oil leaks, the reason this happens is because if they have a leak and they have sludge or large bits of grime that will normally gravitate to the hole and block it. Once you use a good flush it normally will remove all this sludge and grime ready for the new oil, so people will blame the oil flush for causing the leak, however the flush was just doing its job, they have a leak because the car wasn't maintained properly.

Before I put my new motor in, I always flushed my motor ready for new oil, it was amazing after about 5/6 Flushes + Service how much cleaner my rocker gear looked from when I first bought it.

I use the Wynns on EVERY car I service here including my own, have been using Wynns since 1988 and never to this day had a single issue. I have seen some great and often surprising results from using the Wynns products as well over the years.

Even if you have a car with regular services, still use it and also make sure you use the engine conditioner after the change as well

Used it once, got oil leak. lol
Magna engines aren't known as sludge machines, why not change the oil to something cheapish, run the car and change it to synthetic after a few thousand Km?

I have used wynns engine oil flush on my magna when I first bought it, and still use it every second oil change without any problems at all

I use flush every oil change now. Never caused a leak over the many changes I have done in the last 75,000 km. The new oil stays cleaner for longer as there is less residual stuff to foul it.

Oil change ...... that's novel.

IMO, LiquiMoly Engine Detox craps all over the Wynns product... much more effective at stripping sludge. That said, after I did my engine (and ended up with very very very shiny engine internals, I had an issue with clogged tappets, I assume from sludge being moved around, which wasn't a massive drama, just annoying.

Oh really? ALL engines make carbon, this is what flush is for

Using cheap oil is worse again, please dont encourage people to use cheap oil and then fill with synth, is almost as stupid as telling people to overhaul seat belt retractors.....

In regards to the liquid moly I am not sure on what brand however I have always stuck with the Wynns as I have seen the results this product has provided first hand. Both would no doubt have their advantages. Some additives do have tefon and other suspensions, avoid these at all costs for any motor

I have used an oil flush with every oil change in the Magna, and several cars owned previously, without issue. I've used several brands and they've proven useful, most recently Wynns by Mal's recommendation.

I just got my car serviced today by mal (madmagna for anyone who doesn't know) and used the wynns thing on mine, and I gotta say my cars purring like a kitten

Madmagna, can you elaborate on why you don't like the teflon additives. I use the teflon additive in manual gearbox & differential on other non-mitsubishi cars I own and certainly on one of them, I can feel the difference in the gearbox change.

I did not say gearbox as far as I can tell from reading my posts

In the aviation industry Teflon additives are banned, I have personally seen the damage done by additives with suspended teflon and or metals such as brass etc as under high temps these suspensions do tend to turn into big blobs for lack of better way of putting it and many an engine has been seized. In a car, no issue, get a new motor if you dont mind the cost

I used the LiquiMoly Engine Flush (not the the full detox one though) when i did an oil change on the TS a few weeks ago. Don't know how well it worked, didn't notice any "sludge" when i droped the oil but I am not sure if you are meant to see sludge (thinking the engine flush stuff would dissolve the sludge so you don't actually see any whan it comes out?). The car is running smoother but that could just be down to the oil and oil filter change itself. I chose the LiquiMoly stuff purely because it was on sale when i was looking and the can was shiny :P

Going to get the full detox one when I do the oil in the TJ. Was also of thinking of getting the additive they have for noisy tappets as the TJ does have some noisy tappets sometimes on cold startup. Does anyone know if the additives for noisy tappets do anything or are they a bit of a wank?

Anyone ever heard of using diesel fuel as a flush?

Anyone ever heard of using diesel fuel as a flush?

can't say it sounds like a good idea. chances are it would leave a lot of crap behind and would be more of a "i knew i should have bought a bottle of flush" type remedy when you're just too lazy to pop down to repco or SCA. i could very well be wrong though.

Im pretty sure diesel is one of the ingredients in an engine flush, but I recall hearing that using straight diesel is no good for the seals or something like that.

So just stick with engine flush.

I started using wynns in my magna both the oil flush and engine tune up, top product I also use them now in my sri-T Astra.


Danny..

Just to be clear, we're talking about these products, correct?

http://www.autoproducts.com.au/opengineflush.html

I used this on the AWD when I was worried about the Magnatec a few months ago last year. Just let the car idle for 5 minutes with the flush in it and then drained the oil.

Interestingly the rocker covers started leaking around the bolts (just a show of black powder stain). Tightening the bolts a little seems to have stopped that. May be a total coincidence. (I believe the cars life before me consisted of mostly short trips so the constant operating cycle of hot/cold is more likely to be the cause of the leaks.)

I havent tried this, but what I don't understand, is that if these products have such great benefits then why dont the motor oil companies add them to their oils in the first place? (I mean the friction modifier).

try liqui moli MOS2 ANTI-FRICTION for friction proofing no offence to anyone here but i find that wynns products are el cheapo even the feel of the bottle feels cheap and nastey nothing like pouring a bottle of paint thiner/metho with a fancy label into your block since i think thats what most of these products consist of.

When you use the full detox, look at the colour of your rocker arm through the oil cap hole, if they are brownish, they have oil varnishing on them... then look again afterwards.. mine came out as if the engine had just been built :)

I've used Wynns to clear some noisy lifters. Ran it through on the old oil, drained that replaced filter and added new oil... still had noisy lifters. Insert sad face here. Figured I'd just have to take the lifters out and clean/replace them at some point.

Drove the car around since then, maybe done 1000km's in on fresh oil and I now have quiet lifters. Was it the Wynns, or was it the fresh oil? Not complaining. Will I run a flush through it again next oil change? Probably.

Been using this in my 4M40T NJ Paj and my 6g72 MK Triton with the anti wear additive. I felt a difference in power, smoothness and economy. Haven't tried it in my TJ VRX yet.

Wynns tune up for lifters needs to be added to the fresh oil

Oil change ...... that's novel.

Huh? :tired:

Shoot - at $97 for 250 ml it'd wanna be bloomin' fantastic!

Steve

Hmm! If you use a really good synthetic oil (like I prefer, i.e. Nulon or Penrite or whatever) surely any extra additive is unnecessary?

Steve

So the question im asking, is that ive done oil changes on my TF 2.4l magna and the cars done 250klms, and i have never flushed the engine with any flushing products,,,if i start doing it now will i damage the motor???? any info would be appreciated...cheers

Wynns tune up for lifters needs to be added to the fresh oil

I'm thinking my noisy lifter problems need fresh oil, the oil is clear still but it's about time I think.

Luckily they don't have attendants at Petrol Stations anymore or I'm sure if an attendant heard me coming he'd try to put diesel in.
