LIQUI MOLY Top Tec 4100 5W-40 | 5 L | Synthesis technology motor oil | SKU: 9511

Another Liqui Moly review I used this to service my 2006 R53 Cooper S. Has numerous engine modifications so was keen to make sure i used a good quality oil. Being a big fan of Liqui Moly products I naturally chose them again. The engine has done over 100,000 miles but after its latest service you wouldn't know. Sounds better than when it left the factory - or maybe thats just wishful thinking :)

I've been using LIQUI MOLY Top Tec 4100 5W-40 for a while now, and it's the only oil I trust for my car. The quality of this motor oil is outstanding—it consistently delivers excellent performance and keeps my engine running smoothly. The synthesis technology behind it really shows in how well it protects the engine, even under demanding conditions. What I particularly appreciate is the reliability it offers. I’ve noticed a difference in how my car runs—quieter, smoother, and with better fuel efficiency. It also handles cold starts well, which is crucial for maintaining engine health over time. In my experience, LIQUI MOLY Top Tec 4100 5W-40 is a top-tier product that truly lives up to its reputation. If you're looking for a motor oil that provides superior protection and performance, this is the one to go for. Highly recommended!

I use this company since 1995 and they’re amongst the very best!! I wouldn’t hesitate to recommend LiquiMoly, As always you must take care of looking up the correct oil for your application !!!
