Questions about Elf oils

[Wolf_Tm250]

Hello,

is there anyone that knows HTHS values for Elf HTX 830 (10w30) and 822 (15w50) oils ?

And PAO/POE percentages ? I'm not able to find those values on their sites...

PS: given that, according to the oil tolerances I have in my engine ( Toyota 3SGTE 2000cc turbo 425+ 4whp ) I'd like to use a 10w40 oil, could it be possible to mix those 2 oils without any issue ?

TIA.

Forgot to add that Elf does not recommend HTX range as a subsitution of "civil" oils. If I am not mistaken, they said 802 is more suitable for daily use, but again under number of reservations.

If you can't get the info from Elf you can get a range based on the ACEA specs.
If they are rated ACAE A3/B4 the HTHS has to be greater than 3.5.

A1/B1 or A5/B5 would be 2.9 - 3.5.
A1/B1 xw-20 weights could be as low as 2.6.

Thank you guys...

Primus,

You are always a solid source of good information. It appears to me that ELF takes the logical approach that oils should be used strictly according to the intent of their "design." I would follow their advice and use the racing oils for racing and ...well you all get the idea. It is clear to me that Motul takes this approach as well.

 

[Wolf_Tm250]

BTW,

talking about euro oils... especially Motul and Elf...
do you know/could ask the PAO/POE percentages of these oils ?

PS: why Elf does not recommend HTX range as a subsitution of "civil" oils ?

TIA.

The HTX racing oils likely don't contain the detergents that are required in a "street" oil.

Elf's street oils and racing oils are 80% PAO based per my conversation with Elf USA. Don't get caught up in all the Ester hoopla.

I only got caught up in hoopla one time...it was when Hawaii was very popular on the mainland and the hula was the dance to do: you guessed it; I got caught up in the Hula Hoopla...yup, it's all true
