Castrol EDGE Extended Performance 5W-30 Advanced Full Synthetic Motor Oil, 1 Quart, Pack of 6

Oil's ability to lower internal engine friction as much as possible is essential. Engine friction raises engine heat and lowers horsepower output. I like low engine heat and high horsepower output, so I have used successful Castrol Extended Oil for years. Most Advanced and Standard synthetic oils allow higher internal engine friction than Extended Oils.

Always a quality product and worth every penny

Ever since I got my first car, Prius Gen 2, I have done every single oil change myself and used nothing but original filters, gaskets, and this oil. Never had issues with the oil and my Prius always ran wonderfully although sometimes coming close to losing a quart of oil after 3,000 miles. This is in short due to gen 2 having dirty cylinder rings especially being 20 years old and counting. Planning to do a Piston soak using Berry B12 this coming Spring/Summer and will report back how much oil remains but as far as engine burning oil runners, this oil has never failed. Oil is oil at the end of the day, but testing Amazon basics oil for example had resulted in a quart burned after only 1000 miles. Big difference in quality and outcome.

This is the perfect oil for my 2004 Chevrolet Tahoe & 2001 GMC Yukon. I also use this in my 1999 Honda Accord. They run great with zero issues or unfamiliar sounds. I will continue to use this oil as I always have.

So far so good cant net the price !

The best oil that tested in my engine.

Best motor oil of ever used.

Excellent Product, great for high performance cars, made my BMW 535i run smoother and cooler than before also therewould be very faint white smoke coming from the tail pipes some times but after using this oil it stop i don't see the white smoke coming from the tail pips any more. yes i do recommend this product.
