Motul 8100 X-cess 5W-40 Synthetic Engine Oil
  • I just had my 60k service done with motul everything. My engine feels happy like never before and the oil is entirely transparent, with no hint of color. I was in love with my gearbox before, but now I literally want to move to Texas so I can marry it. Motul is amazing and worth the price!
  • He just retired and I panicked over finding this oil because my car runs beautifully with it. I was very excited to find it here. I believe it contributes to my still very excellent mileage and enables me to go 10,000 miles between oil changes.
  • This is the best oil Ive used so far. I have about 4,000 miles on my current oil and am looking to get 10,000 easily and change to fresh oil before the 15,000 mark. I paired this oil with a Mann filter and am running clean!
  • Works like a beast. Car sounds and feels smoother. By far the best oil I have ever used on my car
  • My turbo Subaru runs more quietly and smoother with Motul 5w40 x-cess.
Mobil 1 0W-40 Advanced Full Synthetic Motor Oil
  • No valve noise after i start the cold engine. In hot run perfect and have too much power for twin turbo. I recomended this 0w-40 mobil 1 full syntetic motor oil.
  • its topnotch oil. lasts 12000 miles between oil changes. superior resistence to heat and thermal breakdown
  • For years I've been waiting for these 5qt jugs. I have a MB (Dodge) Sprinter which uses 9.5 Qts for an oil change. Ten plastic containers was a total waste of plastic. These containers, only two required!!!
  • I started using Mobil1 because it is recommended/required by Mercedes for the car I have. Over the 7 years I've been usin it, it has performed very well.
  • This oil is specifically manufactured in accordance to Porsche’s standards. I really like how my Boxster responds to this oil - I feel the engine is running so smoothly. In fact, this motor oil is the one recommended by Porsche for the Boxster

What customers say about "Features"
Motul 8100 X-cess 5W-40 Synthetic Engine Oil
  • I've used Motul 8100 X-cess in my last four Porsches with great results.
  • It is what is says, it's the latest Motul that carries the newer gen Mercedes 229.5 motor oil. The Bottle has an internal pouring spout that pops up and out when you twist and open the top.
  • Very good synthetic oil for high performance engines
  • By far the best oil to use. I change my oil every 3,000 miles on my 2015 Subaru STI Stage 3. Recommend it to anyone with a high performance car!
  • Slightly more zinc than others, which is good. The bottle alone with the built-in spout makes it a winner. Combined with the price and its strong with high-end Euro cars, this is a definite must have. Sold in Liters, so each bottle is just a touch more than a quart.
Mobil 1 0W-40 Advanced Full Synthetic Motor Oil
  • I've been using Mobil 1 0W-40 Advanced Full Synthetic for a few years in a 2007 Saab 9-5 with 2.3L engine with Turbo boost. What can you say about a motor oil? It works fine. 0W-40 oil is less common grade recommended for a number of European car makes (and others).
  • This is the one as a substitute for BMW OEM oil. Even superior. Much cheaper than dealer if you know how DIY.
  • eally a Great Oil. It does meet the VW 505.0 standards applicable for most VW and Audi cars. Many thanks to Mobil
  • I like the fact that there is an extra quart in the container. I have been using this type of oil in my European cars for quite a while.
  • Great oil at a fraction of the price from automotive stores! I use this in 2 Audi and 1 BMW vehicles.
