Repco has a sale on 10 litre diesel oil and filter packs for $59.95 for all you td42 owners out there.
I brought two on the weekend and it seems to be doing what it should.
Does anyone use it regularly? no problem?

yes i did one oil drain and refill with two filters, with that oil pack was good

Used to use it in the old Safari before I got sick of dealing with 10L + of oil and paid oilchangers to do it. I wouldn't recommenced them though.

If its the branded ripco oil filters then watch out. There was a thread on the aussie patrol forum about how they were crap filters and the filter actually came aprt and stuffed motors. Probably a one off, but have stopped using them since then.

The Repco filters here used to be made by Ryco (in South Africa) but after a few failures Repco have sourced the filters elsewhere and they are much better, according to the rep who comes into work anyway.

Ive been using repco oil & filters for a few years now & not had a problem...i figure its only got to last 5000Km so will be fine.
The oil is sourced from Mobil.

Good to know, i used to use mobil delxac mx but the price per 20l has jumped approx $50 in the last year.

I always thought REPCO stood for Rip Every Poor C^%t off

We used Repco oil in the 80 once, was replaced after about 3k kms because of poor performance. We now use Elf Experty 10W40 which is doing well so far.

how do you define poor performance in an oil ??

I believe that the official version of my previous post is
Rip Every Paying Customer Off

We monitor the oil pressure at known temperatures and engine speeds, the colour of the oil and the consistancy. Monitoring is done using the mark 1 eyeball and variations are easy to spot. The Repco oil reduced oil pressure across the range, had a consistancy of water after 3k and was black despite having done no hard work. We have previously used Valvoline Diesel Extra and Castrol (something) and both behaved about the same and better than the Repco oil. The current Elf oil has been in almost 5k and still feels like oil, isn't overly dark in colour and oil pressure is still good across the range which to us means the oil is performing ok still.

back in the day repco was a engine roconditioner on a swap basis repco was reconditioned engine parts company (repco) in nz, there oil fuel and air filters are mostly made i indonesia now and in my opinion are poor quality except for the deisel oil and diesel fuel filters other wise get a ryco,repco oil is now sourced from penrite and is a higher quality , i no because i used to work there and queryed this thouroughly we even cut open filters to compare ryco repco bnt etc to compare and each was differnt to the other naturally

Yep...there diesel oil is no longer Mobil sourced....but ive gone to using Shell Rimula....i wait & buy it on special in 20 litres cans.So far its brilliant ...when i first used it it took about 150 km before the oil showed any sign of dirt.But saying that my motor is almost new.

I know it is an old post, but has raised alot of questions in my mind. I've no knowledge of oils etc, but just want to make an informed choice of good oils to use. This post has confused me somewhat.
I have some questions about the tests, which seem to have some flaws. 1- how could the test conditions be the same. Were they run on a test bed or something?
2-Was it the same motor or a diffferent motor?
3- The mark 1 eyeball is a joke, right?
4- Oil pressure raised across the range? This means that the oil pressure is so low that the relief valve isn't controlling the pressure, right??? Therefore test motor is in a very poor condition. Or maybe the oil filter is different, or it has become clogged quicker because the oil is cleaning the engine.
Lower idling oil pressure, I wouldn't be highly concerned with.
5- Oil not going dark. Shouldn't it be if it is doing its job? Where does all the soot and carbon go then?
From your testing, I'm not convinced which is the better oil, especially when your testing doesn't even test/measure wear inside the engine.

I tend to agree with hemi 265.

You cannot say an oil is crap from your eyeball!! Or out of a controlled environment!! Unless you are doing regular oil samples and notice differences then you cannot say a oil is good or bad!!
However all oils must pass lab tests to meet the api standards. So if it has the same api rating as your mobil mx or you shell rimula the it has passed all the same tests they have had to. And if that meets your engine manufacturers spec then you will be fine.
These engines are not race engines and as long as you are sticking to your oil changes then you will not be creating any excess wear as there is a lot of safety factor in the oil change intervals.

As a marine engineer a engine oil change is anywhere between 20 and 1000 litres per engine so to maximise efficiency we regularly oil sample our oil. Compared to engine manufacturer recommended intervals you can normally get another 50% life from your oils before they start to show signs of losing their
qualities.

I suggested my father to use repco oil(he buys the 20lts) in his terrano for the above reasons 13 years ago and he has done over 250k kms since then! engine is fine no smoke never uses oil and still running strong at just over 300k kms
I did however tell him to not use repco filters, he uses Nissan oem filters.

Just my two long winded cents

Oh and the api ratings for diesels start with C and as follows from wiki,petrol engine oils start with an S.


There are six diesel engine service designations which are current: CJ-4, CI-4, CH-4, CG-4, CF-2, and CF. Some manufacturers continue to use obsolete designations such as CC for small or stationary diesel engines. In addition, API created a separated CI-4 PLUS designation in conjunction with CJ-4 and CI-4 for oils that meet certain extra requirements, and this marking is located in the lower portion of the API Service Symbol "Donut".

just carring on fromnivapulledout

the british consumer did an oil study a couple of years back

they studied the taxi fleet in london (i think)

the taxis were detailed a particular oil co product and put into several groups etc

over 1,500,000mls traveled over the lenght of the study

before , during and at the end of the study the motors were dismantled and all measurements were taken

it was claimed at the end that the oil co didnt have a major effect on the engines life span more important was the service intervals and driving technique

just a bit of usless info

Engine oil is pretty simple, look for the API rating (American petroliem institute), if your running a diesel you should be looking for a C (compression engine) rating, this has extra detergent in it to keep the old oilers clean, you will see API cf, or cg, or ch, etc, basically the higher the second letter after the 'C' the better the quality of oil it is, It really doesn't matter who makes it or how flash the package is, it's what it does that matters (or at least i hope so as I go through about 2000 liters a year in my 4wd's and earth moving gear). Hope this helps some one out there.
Also many oils have a S (spark engine, ie petrol) rating as well, if thats the case and you wont to use it in your diesel, make sure it is printed after the 'C' rating on the label eg Cl/SM not SM/CL.
Now did i just confuse the sh*t out of every one

?

Thats interesting, after reading that i had a quick look online the first oil i looked at was Castrol Magnatec Diesel. It's rating was SM/CF shouldn't it be the other way round if its specifically a Diesel oil?

Then i looked at Penrite oils their Diesel oil had an S/# rating no C/# rating at all?

Most of the other brands had C/# ratings, your right now i'm confused

For all out there, Repco oil is now Penrite. Used to be Mobil. Last two 208ltr drums Ive brought have been Penrite and I personally think its a good product. Nearly all modern oils carry a S and C rating so ok for LIGHT diesel applications, utes, vans etc, anything much bigger should use a diesel only oil which has more different agents added for cleanliness etc.

I did briefly think about responding to you every comment. However the original post isn't the complete in detail report on what we did, just summary and observations, and none of the points raised were addressed in the summary.

The flaw was to write a summary with details omitted so someone can say 'It wasn't specifically stated, so it must be a flaw'. Good on ya.

As for the 'Mark 1 eyeball' comment, if you can't tell the difference between new and well used oil, get an eye sight test.

The point is that companies make a range of oils, various prices with various standards printed on the label. A standard doesn't make all oils with that on the label equal.

no but I could give you a oil sample taken at 250hrs run time that is blacker than a cows 3rd stomach and you might say that it is used(Fucked), however the oil spectro analysis report will say that is is perfectly fine for use for another 250hrs.

the API standards are quite strict and as said if the oil complies to the rating that the Engine Manufacturer provides and you stick to you oil change intervals then you will not have any problems and save alot of cash in the process.
Yes the oils will all vary in quality but the better ones exceed the requirements and unless you are doing spectro analysis you are most probably throwing away that "fantastic" oil that you paid top dollar for halfway through its life.

I think 4wdbits needs an oil change himself. Sounds full of shit to me. I guess he will come back claiming that my hearing needs checking now.
I don't believe that he has done any scientific performance tests to back up his claims.
It's obvious some oils will be better than others even though they are rated the same.
Sure use the best oil, but to say that the lessor oil won't do the job, or has failed some eyeball test is some sort of a joke, especially when one of the functions of a good quality diesel oil is to clean and go black.

sooooo after all that info is the repco oil any good?
Am looking at gettin it for my turboed safari.

Yes as long as it meets your engines reccommended spec and you stick to the oil changes it is good. use a good filter.
