Best High Performance Motor Oils of 2025

"I recently changed the oil in my 2014 Subaru Impreza 2.0L with Mobil 1 Advanced Fuel Economy Full Synthetic Oil, and I've been really impressed! I've noticed a slight improvement in fuel economy, and my engine runs quietly and efficiently. The oil maintains its integrity well, even under different driving conditions. I feel like it gives me solid protection for my engine, and while it's a bit pricier, the fuel savings and peace of mind make it worth it for me."

"For years, I've trusted Mobil 1 for my truck, changing the oil every 5,000 miles. I recently checked under the valve covers, and everything was very clean despite having 100,000 miles on the engine. The oil journals and CAMs looked nice and polished. I believe that sticking with one oil brand throughout the vehicle's life is essential for the best performance."

"I bought this oil at a great price, and it saved me the trouble of going to a lube tech. My husband handles all our car maintenance, so this was a win for me. Reliable and effective without the hassle of a store visit!"

"This is one of the best oils I've ever bought."

"I find it to be great value; my car has been running smoothly for at least 10K miles."

"It works wonderfully; I use it in all my vehicles and I’m saving hundreds on oil changes."

"I've used this oil for years and it's been very good with no issues at all."

"I've been using this brand of motor oil for two years, and it's truly fantastic! My car performs exceptionally well with it. I won't switch brands; this oil provides everything needed. I even use their lubricating grease for my car's ball joints. Great stuff and worth every penny!"

"After switching to Royal Purple, I didn't notice any changes after the first oil change. But with the second one, wow, my car felt brand new! Everything smoothed out and became so quiet. I recommend a 4k to 5k mile interval for the first oil change to clean the engine thoroughly."

"I had been using Penzoil full synthetic for years, but its quality has declined. After experiencing fuel efficiency issues, I switched to Royal Purple. Now, my Honda runs as efficiently as when it was new, and I no longer need to add oil between my 12,000-mile changes. Highly recommend!"

"I've used Mobil motor oil for two years and it keeps my car well protected."

"Buying two from here gives me better prices than Walmart."

"Mobil1 is the only oil I trust; it keeps my engine running smoothly and cool."

"I was raised with a strong focus on vehicle maintenance. My father, a mechanic, taught me about oil changes and upkeep from a young age. I’ve always preferred Castrol, Mobil, and Valvoline, but after researching this oil, I decided to give it a try. After a year and three oil changes, I'm highly impressed. My oil still drains out slightly discolored, which is a testament to the oil's durability and purity. I also use it in my wife's Grand Caravan, and I've noticed it comes out cleaner than before. It truly makes a difference when paired with a quality filter."

"This oil is outstanding! It's essentially the best option for my daily driver. It's made from natural gas, which means it's gentler on seals and gaskets while performing at a high level. I live in an area with harsh winters and hot summers, and this oil handles both extremes beautifully. I do keep an eye on the price, though, as it has gone up a bit recently."

"I use this oil in my family SUV, and the engine runs very smoothly with it. There's no oil loss during the entire drain interval, which for me is around six months or 5,000 miles. I recommend giving the bottle a good shake before use since the additives can settle at the bottom. Overall, it has a solid additive package that works great."

"I really enjoy using this oil in my 1969 Corvette; it performs great!"

"The product arrived in excellent packaging and offers premium quality without the high cost. I'm using it in my 2005 Road King."

"I've been using this oil in my 1984 Porsche 911 for several oil changes. It was recommended for air-cooled engines, and I plan to use it again next time."

"I use it in my 1973 Ford F250 360CI. It runs noticeably quieter and smoother than conventional oil. This is great for older engines with flat-tappets, thanks to the high zinc and phosphorous content. The viscosity index is impressive, making it perform well in both hot and cold temperatures. At around $11 a quart in bulk, it's a great value compared to Amsoil or Redline."

"I've been using this oil since 11k miles on my car. Now at 168k miles, I sent an oil sample to Blackstone Laboratories, and everything came back perfect. My engine has great compression and doesn't burn extra oil. I believe I can easily get another 100k miles out of it!"

"I bought this oil for my 2000 Dodge Durango 4.7L V8 with about 150k miles. I feel I got a great price for it, and it lasts longer than regular oil. This synthetic oil is supposed to add some horsepower, torque, and fuel mileage due to reduced friction. With my driving habits, this oil easily lasts 5k miles without any issues."

"I exclusively use this oil in my race Jeep; it performs great!"

"I've relied on ZR-1 engine oil for my 1977 Buick Regal with 315,000 miles. It's the original engine and has never needed major repairs. I trust Valvoline products completely."

"For my older vehicles, like a 1967 Mercury Comet and a 1973 Ford F-250, I've been using VR1 with extra zinc. It’s worked wonderfully, and I've never flattened a cam since switching from less effective oils."

"I use this in my Ram 3500 with a 6.4 Hemi. My truck has 154k miles and has faced a tough life, yet there's no oil leaking and MDS works fine. I change the oil every 10k miles without any issues."

"This oil was recommended for my Briggs & Stratton LO206 kart motor. I completed an entire season, running close to 30 hours with zero oil issues. It's a cost-effective alternative to other brands."

"As an owner of an older vehicle, I find this oil to be of good quality and it performs exceptionally well. Although I wish it was available in bulk due to my consumption, it's still worth the investment."

"I have used Castrol in my previous VW and BMW with turbo engines, and now I'm using it in my Mazda6 with a 2.5L Turbo as recommended. I've never seen any negative reviews about Castrol. Plus, I appreciate the bag-in-box packaging for reducing plastic waste."

"I'm really impressed with the quality of this oil and the price. The packaging is eco-friendly too, using less plastic, which I find appealing."

"Since retirement, I've started doing my own oil changes. I find Castrol Edge to be superior for my truck, SUV, and classic Mustang. The engine runs much quieter now compared to the oils used by service departments. I just wish it came in a 6-quart Eco Pak instead of 5-quarts."
