Pennzoil multigrade 5w30.
The point you guys make is the key service this forum can provide. Sure, there are people who come to these pages with biases, some built on marketing hype, but hopefully the more (accurate) "field experiences" we share and the more UOAs we see, the farther we will get away from hype and the closer to the real world performance of the products we talk about. Our process isn't perfect but it is better than accepting the slogans in the ads and on the oil containers, or "Well I heard from a friend of a friend of a friend that...." and thinking, "I hope it's the truth."quote:

I find that really interesting, because some guys at this web site say that Delvac is great, and should even be used in cars. How many drivers did you talk to? If it is a lot of drivers, then there is a problem here. I always believed in listening to what people in the field say. You could have what appears to be a perfect motor oil, but if the truck drivers using that motor oil are complaining, then somebody needs to take a look at that.
It is the results in the field that actually count-the real world is what counts. Now sometimes people in the field can develop the wrong perceptions, but if they are complaining, somebody needs to take a look.
I have noticed what you speak of here, a lot of people rave about products that dont do well in the world, and a lot of people are down on products that have perfect real world results. Shows how adept marketers are anymore huh?
At the same time, valvoline has the best performance in the field among racers....quote:

I now use Mobil 1 10w30.
Which Valvoline oils do racers use? From what I see here Valvoline just does not perform the way Valvoline makes it sound.quote:

I published a study of this on the web back in the mid 90's, problem was it was off of an aol ladder so I have no idea if it exists....**** johnson might have saved it, I know he reads here. At any rate, the racers tend to use straight weight, 10/20 for qualifying, up to 60 fo actual racing. Valvoline was by far the most popular oil used of any type. So WHO SAYS it does not perform well? Certainly no one in the field......quote:

Since someone mentioned it in another thread how about Motorcraft?? I use the 5w30 in my 5.4 F-150. No issues except for piston slap and nothing i have tried has made any noticeable difference. What UOA I have seen show it holds up pretty well and is $1.33 at Wallyworld. Son uses 5w20 in his 2001 Ranger and has done well so far. Only about 40,000 miles on it. 105,000 on my F-150.
