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.

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
Ken Robinson
