Diesel Engine Oil

[Whitto]

Have recently bought a 4X4 and it is almost due for an Oil change, It's a 2.8lt 4cyl T/Diesel, Oil's aint Oil's is what Im asking any recommendations or advise what to steer clear of or more too the point what to use, Cheers Whitto

There's many good oil's out there Whitto for the last 10 or 12 year's i've had diesel engine's and have used penrite hpr 50 diesel i change it every 5000 or a little sooner and have never had any oil related problem's.As long as your change's are frequent and not over due i think any of the major oil company's oil's will exeed the requirment's of our engine's in normal circumstances.If in doubt check any of the major oil company's recomended lubricant's chart on their website's.Dan........

As long as you use known brands and of course using diesel specific oil you should be OK.

IMO i like the penrite range as after frequent changes is doesn't seem to leave that tar like substance in the motor like some others do.

I'm sure that someone else will have other opinions but what it comes down to is regular oil changes. (with your T/D you should be changing the oil every 5000km)

Check what the owners manual says in regards to what viscosity you use. if the engine has heaps of kms you can go a slightly thicker oil. So if you have a 10W40 thick would be say 10w50. (from memory)

hope this helps

Thanks Boys, Big help, I know this particular vehicle had regular services, must check the record book to see what intervals it was serviced, It has 225k's on the clock in terms of diesel engines that is not a lot of mileage, The bloody thing runs like a dream, Thanks again, Cheers Whitto

As the guys have stated above the key thing is regular changes.

I have half a dozen diesels at work that get services every 5000k max. The drivers get a toe up the bum if they let it go more than 100km over that mark. Anyway we use SHELL RIMULA D 15W-40 in them with no problems.
Two of the vehicles have done over 500 000km now and still basically havent had anything done to them apart from the water pump replacement and a radiator in each of them.

In saying that its going to come down to how much money you want to invest in your motors over how long you intend to have them. Our work vehicles get a hard life and are not treated with kid gloves ever but they do get regular servicing and that is the key.
I can't see the point in putting high tech synthetic oils in a old diesel thats done 200k or so. Synthetics are a whole lot more exy. If i bought a top of the range 4by for myself brand new i would prolly opt for synthetics to be run from new on.

Whatever you choose choose a HDDO (heavy duty diesel oil). These are diesel oils that have stood the test in big rigs and other commercial engines, they are more sheer stable than most of the crop of oils marketed toward everyday vehicles and they usually hold a higher quality and more expensive formula additive pack for detergents/dispersants/corrosion protection etc.

Put another way the average car/4wd owner uses then dumps, if the engine has not died an oil related death during even relatively short term ownership it is then a good oil.
Commercial operators get their HDDO's laboratory checked for conditon at regular intervals and if the oil doesn't hold up, it shows and shows fast. Very many of the Supr cheep and auto shop oils will not make the standard of protection nessesary.

I use Caltex delo-400, $5.00 per L, semi synth (which really means nothing), CI4 (which means lot's) looking toward the new CJ-4 but not sure yet, very sheer stable, contains molybendum, what else can I say? oh yeah it's a HDDO as well and did I say it was $5.00 per L

Shell delvac 1, is also a very very good oil possibly the best but a person pays for it, too expensive for me.

I've just been using Shell Myrina L in my turbo diesel (4.2) since 1990 with 5000k changes together with filters. Touch wood, no issues to date.

I have been using Castrol RX super in my diesel 4x4's for the last 20 years and NEVER had any issues. I am a diesel fitter by trade and many of the trucks ect that I have worked on have run RX super as well


Just use good filters (OEM or fleetguard) and change the oil every 5000kms on the dot.

Synthetic oil is very very good but way to much $$$$$ for me

[luckyone]

been useing castrol rx super oil for years and cant fault it and you can buy it anywere

[gawby]

All of what you blokes have said is very correct however the success to long engine life is to use the same oil all the time.
Swap and change the brand causes oil useage and motor wear.
I only use R X super in my truck and donot add any other brand.
If i was to use delo or something else that would be all i use.

Graeme is spot on. Different oils have different additive packages that can react with seals, coolers tubes. Best to stay with one all it's life (brand only - viscosity change ok)

[SeaHunt]

I use Shell Helix Diesel, has all the right numbers and so far so good. Change Oil and Oil filter every 5000 K or I might let it get out to 6000 K if mostly highway use. Toyota's hilux manual used to say every 10,000 k up until they switched to the 3 litre motor and then they went to 5000 k.

[catfishkid]

I use Penrite HPR Diesel in my hilux,so far so good.

[GT_warrior]

Interesting that the most of you seem to agree that 5000k is the better interval for oil changes, I am nervous now as I have just purchased the 07 Rodeo TD common rail and the recommended intervals after the first 3k are 10k? What to do?

[Lovey80]

Can hurt to do it every 5000 GT_Warrior except in the hip pocket. At least if you for some reason let it go over then a 10k oil change will get you back on round numbers without any worry?
