Any advantages using Penrite oil ?

Hi. The Penrite website recommends their oil called HPR Diesel 15 for your vehicle. It is a Semi Synthetic oil so is priced accordingly. Supercheap did have it for $75 fo a 10litre container last week but I don't know how long that price went for. I prefer the Penrite brand as I have used it fairly exclusively in a workshop for around 7 years now. No affiliation with either company, just a happy user. Cheers,Bob.

Penrite Oils

Why is Penrite dearer?
BP Vanellus, Mobil Delvac MX, Caltex Delo, and Shell Rimula are about the best oils around.

I am puzzled why people flock to Penrite when it is often dearer. Penrite should be cheaper.

Price doesn't make an oil better.

Many Hilux owners on 4WDaction have changed from Penrite to one of the above with favourable results, ie less oil usage and less deposits in the engine, ie cleaner inside.
Obviously I'm not a fan of it and while many swear by it, other swear at it.
Hilux owners who have changed from Penrite don't go back to it.

It is flogged/marketed in SuperCheap with other "popular in some circles" oils, which to me says it doesn't sell itself by having a sound performance and reputation.

Most of the above oils are not often advertised but make up a large volume of the oil market.

A personal decision of course.

I used Penrite for my trip around z (two years) with no problems.

Got talking to a mobile mechanic in Alice Springs and he used Caltex Super? claiming a cleaner engine and better consumption figures. Tried it for 6 months didn't notice any difference.

My Ford Dealer used Caltex Magnatec (15-30) in my Ford Focus Diesel at service intervals (not the 5 - 30 version as recommended in the manual) and when chipped said Ford were happy with it. How could I query that statement? Stopped going to their service dept and went for Caltex Titanium (5-40).

Been using Titanium 5-40 in my 2008 Prado Diesel for 12 months; can't feel any difference; but I do know that the viscosity is correct even if the cost is a little high.

Been looking at Magnatec again in the 5-30 viscosity range. No real reason apart from the recurring cost every 5,000 service interval.

My garage mechanic uses Hi-Tec but he doesn't have any research information. But he can't supply 5-30 vis. Probably gets a good deal from the manufacturer.

Its all to do with personal preference and whose opinion you value......

Im no oil expert but oil grades are manufactured to certain specifications. Mitsubishi dont make oil nor do they have special additives normally, check your book for the spec and any reasonable brand of oil will be ok! I use Valvolene Super Diesel and my engine has 360,000ks on it and im sure it will do another 360,000ks before it needs work! Michael

I've never bought Penrite oils. I think their advertising misleads the average consumer

To quote their website:
"The Penrite HPR range has been engineered with a unique DOUBLE LAYER of engine protecton with FULL ZINC and Penrite's advanced EXTRA TEN technology"

Haha.......statements like that are a load of rubbish!!! But they aren't alone - many consumer orientated oil companies come up with rubbish claims, with zero objective evidence of any benefit.

I follow the manufacturer's recommendations. They did the research and designed and built the motor. Toyota tell me a 5W30 is best, so that is what I use.
Penrite's recommendations are a 10W40 or 15W50 - suggesting to me that they don't know what they are on about. Couldn't even find a 5W30 on their list of HPR oils.

Barry,
Simple reply.
NO.

barry22,
I had to make a similar decision years ago when BP Vanellus was stopped being made.
I had used this oil since when I bought the Pajero new.
I came across a Lube Oil Analysis done by John Martin who apparently is very high in the oil lube industry. I think he must be some sort of chemist by the way he being able to analyse different types of oil and compare them against others.
I was going to send you a PM but found you were not a member so instead if you go to this link http://www.turbodieselregister.com/Issues/IO57_LubeOilAnalysisII.pdf
You can read all the information for yourself instead of making uninformed decisions based on others experience. Don't get me wrong there is some really good information on this forum and I have learnt a lot during my time reading all of the different posts.
BUT
This article gives valued info that must be acknowledged as having some credibility.
I now use Caltex Delo 400, called Chevron Delo 400 in this article. This was rated as the 5th best oil available for diesel engines and exceeds the requirement for Mitsubishi DiD engines. I have bought it for $90 for 20 litres at major Caltex service stations. Every 15000 Kim's I take a oil sample and send it away to get it analysed. This way I know what is happening to the 3.2 DiD in my 05 Pajero and am happy to say it returns good readings. However I do change the oil every 7500 klms as 20L at $90 does me two services. Cheap as I reckon.
Hope you find the article an interesting read.

The major brand commercial diesel oils have been mentioned.
Caltex dello, shell rimular and Mobil Devlac......they have been independently tested and are 3 of the top 5 diesel spec oils available worldwide ( the top 2 are obscure premium US brands) and the is little or nothing seperating the top 5.

BP no longer sell oils under their own brand, but they own both Castrol and Valvoline.
Valvoline seems to be their budget retail brand these days....i'd stay away.
Castrol RX super, while not up with the other 3 is no slouch and has a very big following.

Ive looked at this issue...I've read the forums and read all the oil spec sheets myself.

None of the small oil companies and second string brands can compete with the 4 major oil compaines in the diesel oil market...not even close....not on oil spec..not on price
These oils are used in massive volume and it is a competitive and tightly speced market.

ALL of the 4 oils mentioned are multi spec mixed fleet oils and will run damn blody fine in both diesel and petrol motors.

ALL of the oil manufacturers sell poorer performing oils at higher prices into the retail markets than their top spec commecrial diesel spec oil.

Get onto google and pull up the various oil specs, any of these 4 oils will absolutely spank the majority of the retail packaged oils on the market.

You should be able to buy any of the above 4 oils for $100 a 20 liter drum....all day...if you shop well, and buy where the truckies buy you will do better.

Persoanlly I run dello 400, and last drum I baught cost me $85 from my local caltex depot

If your diesel is pree common rail,( conventional injector pump) you are looking for a JASO DH1 oil spec....RX super does not quite make it, but it is close.
'Most common rail diesels will require a JASO DH2 rated oil, due to the diesel particulate filter.
Some of the very latest diesels will require a very specific oil....that one is an argument in its self.

NOW a couple of other things if you are starting to service your own diesel.
1>..shop where the truckies shop.....everything is chepaer....everbody that walks into a good diesel spares shop is considered a trade customer...all the small starving truckies do their own servicing...this is where they shop.

BUY your oil filters there.
you will buy a better filter for less money than the retail auto parts shops....you may not recognise the brands...look for Sakura, fleetguard and donaldson.

GO look at the threads on two stroke oil in diesel fuel.
the threads on 4wd action and ausfish are a good place to start.
A hell of a lot of us are finding that our small diesels run better with a little 2 stroke in every tank..200:1 is the ideal ratio

These things I have learned from others, proven myself to be correct and have sworn to tell all that can benifit as thanks to those who told me.

I hope you benifit and do the same.

cheers

Have used penrite since early 90s as bought it initially on mechanics advise to deglaze a motor which was using excessive oil - it worked well.
Have since discovered many other advantages.
Daughter cooked her old 1992 Honda civics engine a year or so ago (it was running penrite despite her complaints re it's price) next day we restarted the engine ran fine and is running as good as ever today. In my opinion she saved herself an expensive repair/rebuild/replacement. Personally havnt done a rings and bearings job on a vehicle since the early 90s so wether that's the oil or better engine manufacturing I can't say but it's certainly a co-incidence. I/we are also keeping vehicles longer as well.
Nissan patrol rear Limited Slip Diffs using Penrites Limslip 140 perform far better on this oil and it seems to rejuvenate old LSDs (The LS140 is too thick for for other 4x4s as it is designed for heavy vehicles you can use the LS90-140 in Toyota and other makes)
Have had good success with Penrite gear oils (over other brands) in noisy and clunky gearboxes.
We tend to keep our vehicles for 300+ klms and simply have had no dramas re lubrication issues.
Like anything these days there is much confusion in the marketplace over manufacturers claims and value for money. I just do my research and spend my money as wisely as I can.
This is just from my personal experience/ choices.
Oh and I better add - No! I don't work for em either!
