What is your favorite motor oil?

I have gotten 136k miles w/2 blown headgaskets, still original turbo, and compression (when the headgaskets are not blown) is still in factory spec. Mobil 1 15w-50 in a 1989 modified toyota supra turbo. I attribute the ability of this engine to take a beating to the motor oil. Also the inside of this motor has been spotless everytime I have had to remove the head.

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.


well I only typically talk to a couple, but of those, 2 are immediate family OO's and one is a friend company driver and they do their share of talking to others.

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?


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."
 
Amsoil 5w-30 in 2K Maxima at 8-9 month intervals

Amsoil 10w-30 in 94 Altima at 8-9 month intervals

Mobil 1 10w-30 in both is my second choice for both cars.

For dino juice either Castrol GTX or Pennzoil PureBase.

At the same time, valvoline has the best performance in the field among racers....
 
First, to John in the ATL----->

Second, to Mystic---->look back at what I said, use both field reports AND UOAs (include VOAs); I completely agree with you...field reports can be biased, depending on the quality and integrity of the source so they should be only one piece of our decision making process.

QD---> I have my suspicions about Valvoline...I have Synpower 5-40 in my car now but I took back 2 cases of All CLimate: (1) because of stuff I have seen here and (2) I'm convinced I don't need to break in my new car with alot of dino before syn...one of the reasons I got Valvoline was because an "ASE certified" parts specialist at a local unnamed auto store said he had heard lots from mechanics about sludged up engines with Pennzoil (same old story) and that Valvoline had a sparkling record (he also said he had NEVER heard anything bad about Fram filters!!!) Point being, what is the real story on Valvoline or any other product for that matter (e.g. do more ASE certified mechanics REALLY use it in their own cars than any other brand...do they do UOAs to support the fact that they do (if they do)...do some of them get it free for "promotional reasons?" Look at the corporate culture in America today...you say what you think you can get by with to sell your product...even if it really S T R E T C H E S the truth. I still insist on the enormous value of this forum even if we have our own questionable sources among us. Hopefully all of us will understand that and be careful about relating our own claims and experiences.

Regards....
 
pscholte, you can get wrong impressions either way-through advertising or talk in the field.

I switched from Pennzoil to Valvoline because I heard so much negative stuff about Pennzoil 'in the field.' I now think that was a wrong impression caused when mechanics saw some sludged up engines and Pennzoil is so popular a lot of those engines were bound to have Pennzoil in them. The problem was caused by poor maintenance and a wrong impression was caused because Pennzoil is so popular.

Well, guess what oil I switched to? Valvoline, which has not looked so great in VOAs and UOAs at this site. Why did I switch? I guess I fell for that advertising-the most popular brand for mechanics.

You have to take all advertising with a large grain of salt.

But you have to be careful with what you hear 'in the field,' also.

And some motor oils have big followings and are hyped big time. There are people who would use some brands of motor oil just because that is what Dad used, or that is the most popular brand, or because they believe this high tech oil 'just has to be better.'

We should look at how well an oil performs in the field and how it looks in VOAs and UOAs. No matter how wonderful a given oil might look on paper, if it does not perform in the field, forget it. And if an oil has sorry VOAs and UOAs I am going to look elsewhere.

You and me are both interested in this new German Castrol. What if the UOAs show that it is really no different than Mobil 1? Then we might as well stop knocking ourselves out trying to find it.

Which Valvoline oils do racers use? From what I see here Valvoline just does not perform the way Valvoline makes it sound.

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......

ps - I had at the end around revision 3, about 300 datapoints
 
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.

there was a recall on 5.4 slap - whole engines were being replaced - look into it.....

Sure do like to throw out incorrect information...

Never was a "recall" on 5.4 engines for piston slap. In many cases, a new or remanufactured engine was installed if the consumer made enough noise at the dealership. The slap has also never been proven to be detrimental to engine life, other than offending the ears on cold starts. Lots of these slapping motors are well over 150k now with no issues.
 
I know we are getting off topic but the only time the slap in mine is really a nuisance is when the temps drop below 40 degrees or so for a cold start. The colder the temp the more noticeable it is. I bought it in the summer before I knew of the piston slap issue and did not notice it until late in the fall. So far at 105,000 it seems to be as strong as ever and the piston slap does not seem to be getting worse. I am hoping it gives me 200,000 like my old 5.0 did.

Actually the synthetic 5W20 does not hit the market until July 15th.

I have to support Bob and a good friend of mine is a Schaeffer's salesman here in Wisconsin. It's always good for a free Brat and cold beer when I buy a case.

Johnny,
When can we get your impressions of the bypass filter. That is if you did get and install it. Just curious on your likes, dislikes.

Tony, br
