Have a car with 120k miles. Works great in there. Have been using it since about 80k miles. Change the oil every 5k roughly.

This oil is just what it says. Certain oils just are thicker even they say the same viscosity I know when I have belt noise or just longer warmup periods.The 75000 mile seal conditioner is a plus.

I have a '09 Ford F150 Platinum. 5.4L V8... Royal Purple gave me better gas mileage by 1.6 MPG. I used a performance K&N Oil Filter (Wrench on) and the royal purple. It's amazing. I believe 100% in this product.

I used this oil and the matching royal purple filter for the first two oil changes on my brand new 2012 Ford Fusion Sport AWD. I shortened the first two intervals to about 4,000 miles to get the initial break in materials out of the engine and then had each oil sample analyzed by Blackstone Laboratories. The Results were perfect! The oil had tons of life left in it and could have definitely met\surpassed the factory 10,000 mile recommendation while providing my engine with maximum protection.

While I understand that there are a ton of folks on both sides of the argument on whether this oil is worth the money or not, I am one of those that will say that I am satisfied with this product. Like many people out there, I am not a chemist or oil engineer, but I have done plenty of research and feel as educated as I can get. I feel comfortable using this product. And I feel even better about investing in it since I found it cheaper by the case right here on Amazon. At the discounted price and free shipping (plus discounted oil filter), a quart of RP oil breaks down to about $7.40. That makes it a bit easier on the wallet.

Too many ignorants and wannabe "oil experts" are on the internet bashing this product. I'd say research it yourself and make your own decision to either use this product or not. I've done mine, and I have no complaints thus far.

Good price, not the best, but I love doing my business with Amazon and its merchants. When it comes to oil everyone has their favorite, Royal Purple is tried and true, it has yet to let me down. Will buy again, also it came well packaged and in air tight bags.

I bought this for 2013 Mustang GT with the Boss track package. I noticed a significantly quieter valve train after the oil change. I've always relied on Mobil 1 and if it is good enough for a nearly $400,000,00 super car it's good enough for my mustang.

Honest reviews on Mobil 1 106035-CASE 5W-50 Rally Formula Motor Oil - 1 Quart Bottle

Pictured is Euro bottled M1 5W50 which is not the same as the US bottled M1 5W50 (which is what's being sold here on amazon). When I placed my order I thought M1 released a new formula, but you'll just get US 5W50 in the regular bottle w/ RED-printing. The reason for this review is because EURO 5W50 is a true synthetic with Group IV or better base stock, while US 5W50 can get away with Group III base stock and still call itself synthetic.

You can't beat the price for six quarts of oil from Mobil 1. This was cheaper them Motorcraft oil and just as good or better. If it's good enough for NASCAR it's good enough for me

Review of Mobil 1 44976 Extended Performance 5W-30 Synthetic Motor Oil - 1

Customer Ratings:

This is the best oil out there for the regular driver who wants maximum protection for the car's engine. A little research brought me to the Mobil 1 Extended Performance line of Synthetic oils when searching for a product that could allow me more time between oil changes. Mobil 1 EP allows a 15,000 mile/1 year guaranteed life of the product. I have been using this in combination with their Mobil 1 filters for years. The cost is higher, but I only need to change the oil once a year!

Originally developed for aerospace, synthetic oils became commercially available in the 1960's. Some technical advantages Synthetic Oil has over Conventional Oil are [from Wikipedia]:

Measurably better low and high temperature viscosity performance

Better chemical & shear stability

Decreased evaporative loss

Resistance to oxidation, thermal breakdown and oil sludge problems

Extended drain intervals with the environmental benefit of less oil waste.

Improved fuel economy in certain engine configurations.

Better lubrication on cold starts

By using a Synthetic oil not only will your engine be able to perform better, but it can also extend the engine life. I HIGHLY recommend use for those with more severe or high demand driving conditions.

Amazon is my source for buying so many things, and I am a satisfied user, but we do still need to check locally. Mobil 1 oil is on a promotional sale at Advance Auto -5qts plus free Mobil 1 filter($10)for $30. Of course, it's an excellent oil with the EP version permitting 15,000 miles or 1 yr(I wouldn't really go that far myself)between changes. It can be economical to use since less oil changes can more than make up for the additional cost of this synthetic oil.

From having worked in the petroleum industry test industry, I learned from our customers that Mobil 1 has been the pioneer and the performance benchmark for synthetic lubricants.

From personal experience, I have used this product in my vehicles, both classic and contemporary, for more than fifteen years or easily 2 million miles without an engine failure.

Though it is rated for 15,000 miles, I plan on changing it every 12,000. Still a huge savings compared to 3000 mile oil changes at the dealer.

Hard to find, but worth it.

I always run 7,000-15,000 miles between oil changes. Motor has 80K using this oil. Still runs like new.
