Red Line 15405 SAE 5W40 Fully Synthetic Motor Oil - 1 Gallon

Did what it said on the box

Just got done doing an oil change on my Ram 3500 6.4 and prior to doing so I was extremely excited because of all the reviews on how awesome this oil truly is.My Ram has always had the Hemi tick buy just recently it became obnoxiously worse to the point I felt I had an exhaust leak. We travel the country now full time towing our RV behind and I really just wanted an oil that offered more protection, protection that was proven right, cause they all clam they’re the best and I wasn’t looking for actual test etc cause they can be manipulated too. I was looking for true reviews from people that have purchased and got results either way.I was happy with what I saw and purchased the oil and got a K&N oil filter and preformed the oil change. Easy peasy.To make this long story longer I turned the truck over let it idle for a bit checked the oil but unfortunately the tic was stil there… I was disappointed but not shocked. I decided to take the truck down the block a bit @5 miles or so and came back. Before turning the truck off I noticed the tic was wayyyyyy less noticeable and was stoked to say the least.Went inside came back out after an hr or so turned the truck over just to make sure and bam the tick was 98% gone…. I’m so excited and grateful for this experience. Also when I would drive normally my oil pressure would be @ 49-51 and now its more like 52-54.This was definitely a way way long review but the bottom line is this stuff is the Hemi Tic Kyrptonite! 😊 If you’re on the fence on this oil and it’s capabilities jump off cause its the real deal for sure!Also I see people talking about how expensive this oil is, not really compared to orher top line oils and you always get what you pay for and this product is a prime example.

I drive Bmw 550i this oil is by far the best oil available. There’s a near instant difference between this and the common oils everyone uses. The motor immediately sounded better on both warm and cold starts,as well as an apparent increase in gas mileage by around 20% due to in the increase in lubrication. I would only put this in a car that’s either high end or you’re a person with a heavy foot or both. It’s very expensive but it’s worth the cost.

I have a Fiat 500T, and with the factory mandated oil (Pennzoil Euro Ultimate), I was having to add a quart every 1200 miles or so. This is certainly within reason considering how I drive(lots of high RPM, engine braking, etc.) but I was really getting tired of having to add a A)really expensive and B) very hard to locate oil so often. I am about 700 miles past the oil change to Red Line, and there has been NO change in the oil level. This is a new development! Would normally be pouring a half a quart in right about now. Runs as well, if not better, than it did with the unobtanium Pennzoil. I will update this as I go along, but for the money, this seems like pretty fantastic oil, and so far, demonstrably so, at least as far as consumption goes. It is no more spendy than the factory fill on this car. I am going to send a sample to Blackstone at about 5000 miles in to see what's what.Good stuff thus far.

fast delivery and no damage!

We use this on all cars now

I've been trying various 'top-shelf' oils (Liqui-Moly, MOTUL, etc, etc.) Redline motor oil is definitely up there. Motor seemed to run quieter and a little better MPG's after changing with Redline. Seems like a good product. Not surprising, their transmission fluid is second to none.

Best full synthetic oil found in this weight. However, the manufacturer knows that and charges plenty for the product. This oil performs the best in my engine according to the oil testing reports; if not for the price, I would give 5 stars. If I couldn't recoup some of the extra cost by extending my drain intervals I wouldn't spend the extra for this oil. Seller performed as they should; even though I didn't need to contact. Product arrived on time.
