Could someone here please share their take on Liqui Moly Synthoil High Tech 5w40 for year round use? I believe Liqui Moly is labeled Lubro Moly in the states.

It's an API SM. How good is it? I'm only really concerned with wear protection and deposit formation prevention in severe driving conditions. No extended drain. I change my oil at 5000 miles. 7000 tops.

I'd also like to know whether their 5w40 weight diesel synthetic (Liqui Moly Diesel Synthoil 5w40) is better seeing as how it's only rated an API CF (no S rating at all, I'm guessing it wouldn't qualify SM because of the wear additives so they never bothered to put it up for S certification) oil and perhaps (hopefully?) contains elevated concentrations of antiwear and dry lube additives like MoS2, ZDDP.

Where I live you can get it for a little under USD 100 for 5 litres. This is what I currently use.

A tribologist on http://www.s2ki.com said Lubrication Engineers formulate the very best lubricants in the world so I wanted to know whether these two come anywhere close.

I want peace of mind and the very best consumables I can readily get for my car. Unfortunately, it's very difficult to get a hold of exotic US synthetics where I live.

Despite the wonderful things I've read about Amsoil and Redline they're a pain to get hold of here so I'd also like to know how well these 2 oils stack up against similar weight formulations from Amsoil and Redline.

I drive a Peugeot 206 2.0 HDi(common rail turbodiesel). Model year 2000, 26500 miles on the odometre, almost entirely relatively demanding city driving.

I change anywhere between 3500 and 5000(redlines at 5000) on the tach when the engine is warm. I always idle her 10 minutes before setting off (it takes about that time for the idle to settle down to 750 from 800-850 ~ normal, low idle) and change at 3000 tops until I'm satisfied the engine is thoroughly warm.

Which is a bit of nuisance as I've no oil temp. gauge and am very paranoid about doing right by my car.

And one final question.

Are WS2 and MoS2 any good? Anyone know a readily available WS2 additive manufacturer?

Many thanks. Cheers from Europe.

Peugeot 206 2.0 HDi(common rail turbodiesel), should you be using a low SAPS , low HTHS oil like me.

Look at Total Quartz 9000 0w30 or similar Elf or Fina First oils.

They where made with Peugot/Citroen/Ford diesels in mind
 
10 minutes is how long it takes to drop from high idle to normal 750 idle. Apparently irrespective of outside temperature.

I don't commute using the car so it's really not that much a hassle. I don't think it harms the car. On the contrary, I expect doing an UOA would show more wear if I didn't idle it so long.

I'm already using the Liqui Moly 5w40 Diesel Synthoil. Been using it for 1500 miles. Just want to know if it's a top tier choice and how it stacks against other synthetics in engine wear. Preferably from UOA of ppl. who've tried it.

And also whether anyone's tried the MoS2 add. and what you think of it, if it lowered wear as far as UOA can show.

your 10 min idling habit is more harmful to your engine
than the oil you use, but if you like to dilute your oil with diesel its a good method. just start and drive after it has been steady running.
avoid additives.
 
I currently use Lubrication Engineers products. The Liquimoly products are top-tier as well. I will actually be using their 5w-40 synthetic in a Porsche that I have arriving in the Spring. You cannot go wrong with the Liquimoly products at all. Porsche uses them as a factory fill supplier in Germany.

Your are confusing the company name with the product name.
 
I am also using this oil and for now nothing wrong with it... I'll try to do UOA but this is not that common where I live

The only thing that concerns me is 2 details in tech sheet: flash point and viscosity index, both to low

Any explanation (Maybe more additives

)

Viscosity class : 5W-40
ASTM colour : 3
Density at 15 °C : 0.85 g/cm³
Viscosity at 40 °C : 87.3 mm²/s
Viscosity at 100 °C : 14.1 mm²/s
Viscosity index : 138
Flash point : 193 °C
Pour point : -42 °C
 
Hi,
The VI is a typo-should read 168

http://www.rohmax.com/rohmax/en/customerservices/calculationtools/viscosityindex/

The technical data sheets on LM site haven`t been revised since 2006,and the material safety data sheets(dating 2008)reveal identical products now.I think Diesel Synthoil is going to be phased out soon,as the online recommendation chart doesn`t list it anymore. In my opinion nowadays the difference between Diesel Synthoil 5w-40 and Synthoil High-Tech 5w-40 is only on the labels of the cannisters.
Here are the documents:

I wouldn`t be worried about the flash point..and it seems kinda low for a COC method...I bet the document is incorrect.
and here is a Synthoil Hi-Tech doc from 2003:(with the wrong numbers)...
http://www.belautogroup.by/image/pg3/p64im3.pdf
..so 1.the two oils IMHO are identical(have always been) and 2.The flash number is probably given wrong.
