Comma SYZ5L 5L Syner-Z Fully Synthetic 5W30 Motor Oil

Iv gone between Comma Syner-Z C3 and Castrol Magnatec C3 with BMW LL04 specification for my M57 diesel engine. Im not an engine myself so cannot tell the difference but there have been no issues. My engine requires 7.5L so its £120 ish (!!) for 3x 5L which makes up 2 full oil changes. I will look to Westway Oils next time as i change my oil 3x more often than BMW LL service intervals so there is a good saving to be had. Your milage may vary if you arn't as DIY and leave the oil in for longer intervals.

I have been using Comma oil products for well over 15 years now in my cars. Current car is Skoda Octavia with a PD130 engine which needs a good oil because of the high pressures involved with the PD series of engines (involving an extra cam to pressurise the fuel to feed direct into combustion chambers) My engine has been running fine on this particular oil for the last ten years with no problems with the engine at all. I have changed the oil once a year on a mileage of 8k or so miles a year. I find that it hardly needs any topping up over the year either, so i am a happy customer for this particular oil.

Have used this for a few years now in a diesel Mercedes. Change every 10k and doesn't use a drop.

Excellent product used this oil for 50 years..

Use this in my Lada Niva as Comma recommended it. Very oily as expected. My Niva jumps for joy after every oil change

Thanks guys, quick service and good price

does what is says on the container.

Excellent quality ACEA C3 & SM / CF spec fully synthetic 5w30 motor oil. I use this is both my Volvo 2.5t petrol and D5 diesel engines, and have been doing for the last few years with no issue. I would say that the engines tun better than they used to as well despite being 10 and 9 years old respectively
