Engine oil OEM Mazda or Mannol

Any oil that meets the manufacturer's specification for your car will be fine. Mannoil 5W30 fully synthetic meets VW 502.00 and ebay sell 5L for about £17 - why pay more?

Definitely better well known brands out there for cheaper prices. Look at Mannol oil. Mannol served me well.

I use Mannol. 5l of the stuff in 5w-35 retails at about £20 on eBay which is a damn good price.

I've always had good luck with manol oils.

2014 3, 0W-20 full synthetic (whatever major brand is cheapest) from brand new, every 7500 miles.

170k, runs like a top, burns not a single drop between changes, compression and fuel mileage exactly the same as new.

Oi analysis came back and no extra signs of wear... Mannol is great oil just change at 5k and add in oil additive such as ceratec every other change

I've used for the last 20k miles and no problems! Just change at 5k.

I use Mazdas 5w-30 Ultra DPF. Mazda once said that this was the oil that they're using, so I guess what's used by mazda can't be too bad for the rex

Personally I use 5w-30 because it's the cheapest. I've used 0w-20 and 0w-30 in the car also. Can't tell what is in the car at any given time as it runs exactly the same regardless so just use the cheapest that's still up to the relevant specifications.

Mannol is cheap for a reason as you never know what you will get in a bottle.
