(06041-6PK XPR SAE 10W-40 Synthetic Racing Motor Oil - 1 Quart, (Case of 6)

History has shown this to be one of the best oils available. I highly recommend it.

Just get it.

Royal purple is worth the money quit being cheap

As I am a bit "over the top" when it comes to maintenance and anything that will improve, extend and increase the longevity of all our ranch equipment (a 35 yr. old log splitter, a 1973 F-250 plow truck, my shop equipment- etc.) I had an ASE Certified shop install a NEW 454 from GM in my 1994 K-2500 4x4, not wanting to spend $40,000 + on a new truck (I don't think the new ones are made to last anyway) I broke in the new engine with RP break-in oil, 3 changes in 5,000 miles. At 21,000 miles I decided to give the "Cream of the Crop" RP oil a try, every fluid in my truck and my 77 yr. young mother's Toyota Tundra is RP- This XPR is the very best in every way for what oil is supposed to do, it is very costly, but so is a new engine or truck. We (my mom & I live 75+ miles from any town w/ more than 380 folks) When we have 16 -18 feet of snow and temperatures below -10 for days, weeks on end and summers above 100 I won't trust our lives to anything else. I saw an increase in MPG by 2-3 and much snappier response, at 60 MPH I get 15 MPG ,off-road in 4x4 mode I can't say but my fuel lasts longer- as the old saying goes "you get what you pay for" Thanks Royal Purple for a wonderful product, and to all who take the time to write the reviews- A big Thanks to Amazon for the ability to shop so far in the backwoods

I have been using this oil for the last few year's in my cars-wife's 2000 Monte Car SS, 1987 Buick Turbo T Grand National, 1998 WS6 TransAm LME 427 Twin 6466 Turbo's and a Generac Generator which proved that it can handle running for day's without issues.

This is the best oil out there, no valve noise at all. You never have to worry about a dry start and it lasts over 5000 miles.

Is a good deal and allows me to reuse the big container for used oil or other liquid storage if needed. Nice recessed handle. Don't have a bunch of quart bottles to deal with and then recycle. I pour into a two quart pail and use a funnel. Filling goes very quickly.

Royal Purple is the best oil for any engine. The XPR (Extreme Performance and Racing) line is the best of the best! I use the XPR in my 426 Hemi engine, which sees hard use on the street and at the track. Not sure what oil is best for your engine? Call the engineers at Royal Purple and they will be glad to make a recommendation for your specific need.

ロイパ音がちいちゃくなって素敵です。 も少し安かったら嬉しいです

今のところオイル交換で違いがわかった 、唯一のオイルです。 冬の冷間時に始動も良ければエンジンも良く回る。

入れて走り出した瞬間に違いがわかります。 エンジンがスルスルと回転してあっという間に最高回転まで回ります。 下から上まで振動も少なくなります。 色いろとオイルは入れましたが最高のパフォーマンスです。
