I read the recent posts about frequency etc and thought I'd start another one with regards to engine oil.
I've got a 99 GU 4.2 TD Patrol ute. I recently changed from Castrol RX super which is 15W40 and a CH4 grade to Penrite which was also a CH4 but is 20W60. I did this as I live in the tropics where the manual suggests 20W40 or 20W50 for warmer climates.
The thing is, Castrol has released an upgraded RX super, now CI4 and the price for a 20L drum is around $81 compared to $95 for Penrite.
Should I go back to Castrol when the next service is due or is the difference in quality insignificant.
I paid the extra in the first place as even though they were both CH4, the 20W60 was more applicable for me and I also went on the old "if it's dearer, it's usually better" approach.
Thanks.

Thicker oil may not be better. Engine wear occurs on startup, and thinner oil gets to the top of the motor quicker.
I'm sure it won't matter two hoots to a Patrol 4.2, but I'd be happy with the 15W40. Likewise, CI, CH, CF etc are all the same to a 4.2 Patrol. Whenever I've phoned Castrol, they've suggested their CRF or GTD oils, which are often considerably cheaper.

Phil, I am a bit confused about the diesel oil categories and the current sulphur content in fuel. In the API motor oil guide, CI and CH refer to use with fuels with sulphur contents up to 0.5% weight. CF refers to sulphur content over 0.5% weight. Toyota recommends CF-4 or CF for my current model Prado. What is sulphur content of currently available fuel??? Will we need to change to a different oil category when the sulphur content is reduced again???

IAB,
You're not the only one! Like you, I own a Prado TD, and use CF-4 grade oil because thats what Toyota says to use.
I know nohing about the effect of lower sulphur content on the grade of oil.
But the way I figure oils, the diesel motors last 300-500,000km on normal oils. So why would you want to use anything "better". Too much hype about Synthetics, and it seems a shame to fill expensive oils with soot.

Mine is a 99 GU 2.8, always used Shell Helix but now use Castrol RX Super 15w40. Personally, I would stay with Castrol or Shell

Penrite is a far superior oil.

I'd be a bit wary using a 20W60 when Nissan recommends a 20W40 or 20W50 oil for warmer climates. The 60 weight oil may just be a bit thick and is usually used in engines that have a lot of wear in them and wide tolerances so as to keep oil pressure up.

I reckon you would be hard pushed to notice any difference in the top name oils.How would you tell just by driving or even looking at a stripped down motor?Saying that your engine lasts longer because its using brand x is just bunkem. The oils all come out of the ground and probably from the same region.
Its far more important to change the oil and fiter reguarly and keep the engine well tuned to stop a build up of carbon that will clog the oil up. Keeping the cooling system working perfectly is another thing that ensures long engine life.Hard acceleration, frequent cold starts and short trips destroy a motor far quicker than choice of oil.

"The oils all come out of the ground and probably from the same region."
WRONG !
Type 'synthetic oil' in your favourite search engine and do some research.
We use top grade full synthetics in every 4 stroke in the place from Brigs and Stratton lawnmower to trucks and generally can claim 8 to 10% fuel consumption improvement, much longer service intervals, easier cold starting, and much better internal cleanliness.
My 600cc enduro bike used to give me around 300 K to a tank before switching to reserve. With a change to synthetic - it now goes to 330 K.
More expensive - YES
Would I consider reverting to the mineral oil that comes out of the ground - NO WAY!

Evening everyone.
Whilst on the subject of 'which' oil.
Has anyone either heard of or experienced a product called BIMROSE oil and lubricants that is distributed out of
Queensland.
Its on the WEB, however I have asked this question twice before in this
forum and there is a deafening silence except for one lone voice who stated that he used it and liked it.
C'mon you Queenslanders, nows the time to 'out' yourselves and share your knowledge/experience of this product
If you don't want to say anything in public, please contact me on ken_3149@yahoo.com.
Thank you for reading this

I have often heard that it doesn't matter which brand of oil you use, just stick with the same one all the time. Not sure where that idea originated or whether there's any scientific backing for it.

In reply to tuco69 The current debate was about top name mineral oils and the price and it was to that I was referring.You are the 1st to bring synthetics into the debate which are not comparable in price .

Bimlube are repackagers of oils, I know they use some penrite products repackaged under their own name. ( Limslip 140 and ATF Dx 111 being at least 2 I know of).

Thank you for that. You are only the second person on this
forum who has acknowledged knowing of Bimrose Oils & Lubricants.
Your answer has shown me the light at the end of the 'tunnel' and my 1H troopy will remain on Penrite with no additives.
Thank you
