MOS2 or Bardahl turbo protect

Hi,

In few miles i`ll change the oil with 0w40 mobil 1 or 5w40 mobil delvac.

I wonder to put a additive in the oil.

What is your opinion for better lubrication in cold.

There are some analysis

What do you think Delvac 1 or Mobil 1 are lacking?

What type of engine is it? What are the conditions? If you are looking for cold weather flow in a robust oil, it's hard to beat a synthetic 0W-40.

I can't see how any additives would help if that's the case. Mobil 1 0W-40 is quite a robust oil.

I translated the link you provided and they seem to promote a ZDDP additive. It's well known that ZDDP is the gold standard for flat tappet engines, I'm not sure what engine you operate. Possibly it won't help a thing if you have a modern OHC engine, and you use a quality oil.

Both Delvac and M1 0W-40 are robust formulations. The Delvac will be considerably more resistant to flow under extreme cold.

Bardahl?

If you must use an additive, use the MOS2, but if you're using good oil, why use an additive?

When Bardahl says turbo they are trying to say 1992 Dodge Spirit.

Bardahl was once the largest seller of motor oil in the US. When the A.P.I. came out they refused to comply, threw a temper tantrum and withdrew from the US. Most of their products are made in Mexico, their biggest market is Mexico, and they also do quite a bit of business in SE Asia. Their headquarters are still in Seattle's Ballard neighborhood.

Definitely not the Bardahl quality of the 1950s.

My engine is 1.6HDI It`s a Peugeot/Citroen engine.

My user manual says -5w40, because i`m withou FAP/DPF

I change the oil 3 times in year (5000/6000 miles with oil) and every winter I change with thinner oil like 0w40/0w30 Castrol Edge Or Total

I read a lot of good comments for Delvac 1 5w40.

I just wanted to insure and improve with the addition of engine addetive
therefore sought advice on additives

My car is around 135000 miles.

I don't have a turbo engine however I suggest emailing liqui-moly before using a solid lubricant in a turbo application.
Mos2 is great stuff and I use it in everything I own. I don't have a turbo though except my forklift. I used a can of mos2 in it once. Saw no difference in fuel consumption so I never used it again.

Turbo engines do last longer on full synthetics. As the synthetic base stocks don't coke up the turbo and piston rings.

Additives generally don't use synthetic base stocks. As most synthetic base stocks are not good "additive carriers". Simply put, you may be adding a product that will oxidize easily and coke up the turbochargers hot side, piston rings and other hot spots.

I suggest using a high quality synthetic and nothing else.
