I think the point the poster that you quoted was trying to make was that Royal Purple states that if you replace ALL the fluids in your vehicle (tranny, diffs, engine, ect) that you will increase hp and mpg. I know it doesnt mean much but i remember when horsepower tv put a camaro on the dyno, ran it, then replace ALL the fluids with RP and they gained 8 hp.

When BP did the blind test, it was on motors only, not in test cars on dynos.

Anyways, its everyones personal preference.

 

132K miles and I bet it is just as clean as yours.

 

guess i have been lucky over the years using amsoil-once a yr oil and filter changes,zero engine problems in almost 2 million miles of use in my personal; and company vehicles...

 

Amsoil is designed for extended change intervals.

 

Amsoil does claim extended oil intervals but also recommends an oil analysis at certain mileage.....more $$$ and time than it is worth for most of us. I ran whatever I can find that is within spec at the lowest price.....right now ,that is 6 jugs of Valvoline conventional followed by 4 jugs Mobil 1000. Bought these for around $10 each and run them 10000 kms without batting an eye.

 

another oil thread !!!



SWEPCO....

The principal is the same. Seeing how they did a test on the engine and only the engine, and saw zero gains in this engine, how would it translate to anything by adding a car behind it? Their motor oil is advertised to gain MPG. Their motor oil is advertised to reduce friction wear and lower temps. This blind test apparently proved these advertisements (not the product itself) wrong. They do not make a substantial enough change in any of those categories to be advertised as such. (now someone needs to do this for K&N and other CAI rip off artists).

Guess it doesn't matter that there are plenty of motor companies running Mobil 1 and now running into sludge build up issues. I have told you this before, yet you seem not to mind. Synthetic does NOT = no sludge. Period. End of story. Synthetic can sludge just like dino oil. Can be dirty, just like dino. Proper maintenance and care is what is key here, not the type of oil you use. If you go 400k, you can brag about your maintenance record, not the TYPE of oil being used. I have said it before, I'll say it in every retarded, stupid oil thread, its YOUR truck, and YOUR money, do WHATEVER tickles your fancy.

Damoose: Who do you think paid for that little advertising stunt ? If you go ask Tiger Woods what is the best sports drink, his answer WILL be Gatorade. If Vitamin Water decided to pay him more, I am sure they would quickly become the "best". I am sure RP offered up some sponsorship and advertising money, in order to run that little promo with some "outside" people telling you how good their product was. Nothing wrong with it, but don't believe much on those "power block" style shows. They are advertisment for the aftermarket ( well... sort of ).


Anyways, to each their own.

 

i get ya, they were basically doing a synthetic vs regular motor oil test. Im not saying that RP will give those gains over any other synthetic. I use Mobil 1 synthetic and change my oil every 3000 miles no matter what. I think ill be alright in the long run using Mobil 1 and changing the oil every 3k. I did put RP in my differential though. Im a synthetic fan is all, doesnt really matter which one.

Id like to know what oil you mechanics use in your truck

 

I use Mobil 1 EP and a Mobil 1 filter and change it once a year - which is around 10k.

 

I'm sure you'll be fine. The guys running into any issues with Mobil 1 are the guys trying to go for the extended interval changes. You start waiting 10k+ before an oil change, I don't care what oil you run, but your going to have some gunk. Also not saying RP is a bad product. Couple buddies run it in the diffs also. As long as you don't buy into the extra hype, and know what your getting, your fine. Nothing wrong with synthetic or RP, but there is nothing wrong with good ole Dino oil either.

As for my oil, I run SWEPCO in everything from my truck, to my samurai, heck even the lawn mower and other misc crap I have laying around. It's some seriously good stuff. It's just too bad it isn't sold over the counter. All their oils and greases are just kick butt products.

 

waiting for 10 k+ oil changes = gunk-LOL
2 million miles in my personal vehicles and company vehicles using amsoil and amsoil filter -once a yr changes-NEVER AN ENGINE PROBLEM TO DATE,and i go wayyyyyyyyyyyyyy over 10 k miles on a change

 

Amsoil does not recommend oil analysis to meet their change mileage requirements. They do this on diesels, but not on gas motors. Their published recommended mileage change intervals are just that...guaranteed. For the diesels, they do not list a mileage that the change interval is good for. They recommend oil analysis to determine how far you can go...only on diesles.

 

With a bypass filter, you can go 100k plus with Amsoil.

 

Me too.

 

Labnerd, Do you have the original article saved? I'd like to have a look at it
