I really dont find it all that hard to believe...

if you look at hydrodynamics (the way liquid flows) replacing a luquid with a less viscus liquid will lower resistance (but may up friction),

but this is more an issue of oil weights than being synthetic or not...

and in extreme conditions this may cause more harm than good....

I.E. really hot or cold, really hot oil will become too light and fail to lubricate properly, thus causing engine dammage.... really cold if the oil is too thick, it wont flow, and dammage will follow...

but I believe this 10 hp increase will be at the expense of some engine/driveline part.

Of course, with forums it's hard to tell too, theres been a lot of PRESS lately on advertising marketing companies hiring people to "get known" in forums to then plug product. Apparently, it's now now SOP for a lot of product that has huge Net followings. (Cars, omputer equipment, etc)

I want this job XD

 

[tc3driver]

Nah...

If I could do it from home... I would do it...

but as for posting about things I like on a forum... all happy about it...

I do my own vehicle maintenance, how is a dealership going to know when I change my oil?

All I can say to you is, IF and I mean IF you have an engine problem (trust me I have been through it), they may demand reccords of your oil changes, I'ts not hard for a mechanic to look inside an engine and see how often the oil has been changed, typacly a motor who's oil has been changed at irregular intervals and who's oil was left in for long periods of time will build up sludge, and believe me, it saved my *** that I used mobil1 and changed it every 3k, even though I couldnt produce the reccords, the mechanic, my last car had the engine replaced at 42k, said the engine looked like it had less than 3000 miles on it, and if it werent for all the metal flakes everywhere he would have thought that nothing was wrong.

but they can tell... it is not hard to tell...

especialy if you have been abusive to your car (not implying that you are).

and synthetics do buildup sludge, just takes a little longer for the sludge to build up. but it still breaks down over time. dont believe me, I can put you in touch with mechanics who service nothing but cars that come from the factory with synthetics.

while yes, synthetics are suposed to last longer... they will still break down, will still sludge up... and will still be evident as to abuse via infrequent oil changes.

I've been using Royal Purple in my Hardbody since I bought it w/ 28,000 miles (now 69,000). I plan on switching to RP w/ the Frontier. I have 250 miles on it now. Do you guys have any objections as to why I can't switch to RP at 1,000 miles?

Also, this converstion made me think of something. What can the home mechanic do to prove that he/she has been doing regular oil changes, etc? Keep receipts of materials bought, although that doesn't prove that they were actually used? How has everyone else been doing this?

I'm waiting until I have 6500 on it...

only because I think that the engine should be fully worn in by then (well it is a nissan probably wont be broken in until it has 100k on it ) but yeah....

that and I change my oil really frequently douring the early months... I am only 1k away from my next one at 3k... then I'll get it done at 6500... and switch to synthetic.

I've said my piece...

I stand firm on what I have said...

and you just do that 12k mile thing between oilchanges...

when the dealer asks when you last oil change was... what are you going to tell them..

"you see... I run this mythical oil called amsoil/Royal Purple, the manufacture of the oil says it is good for 15k..."

they will laugh at you and stamp your warranty on your engine null/void.

I would rally like to see this oil after 12k miles...

I mean you do realise that sludge, grime, and what ever other name you want to give that sicky, gewy, slimy stuff that rests on the bottom of the oil pan, and affixes it self to other non moving parts.

it's composition.. mainly dirt, and carbon.

my point stands... they will then open your engine and show you the "crud" that is everywhere.

It is not like I am as ignorant as you say... I was born into the world of autos, my grandfather was a car collector, my father is the service director at a local benz dealership. whom they call to GERMANY to trouble shoot cars... what he says is biblical... change your oil.

I can have about 50 techs call you right now and tell you different.

look I am not doing this to be arguementitive...

but going 6000, 10000, 20000 miles between oil changes is not a wise move. no matter what oil you use...

but worse... our engines only hold 5 quarts of oil, that is not much oil... where as a big rig can hold about 55 gallons, and will typicaly go 100k between oil changes...

there are a lot of variables here... and changing the oilfilter and not the oil, is well dangerous... you have survived... I am happy to hear... but all it takes is the wrong person to percieve something wrong... and we have blown engine city... or we create a place where manufacture suggested oilchanges are completely thrown out the window... any time you do that, no matter what oil you use... will void your warranty... that is why this truck will see nothing but the dealership for services... and I'll be doing it every 3000k, even after changing to synthetics...some say why?

cause I care enough about my trucks engine to want to change the oil after 3k....

I am going to do my own reserch on these products, and I'll see how many problems have been attributed to it.

if there are none that I can find... good for you... doesnt mean that I am going to change my religion of oil changes....

how about I put it this way... just because you can jump off a cliff... does that mean you have to?

in other words, just because you can stave off changing your oil... does that mean you have to?

both are deadly IMO...

so go your 12 15 20k with out oil changes... but if something (god forbid) goes wrong... dont ***** about it when they laugh at you for trying to get some warranty work done.

how bout 250,000 on my jeep... i was not the first owner, but he also used AMSOIL, i only had it for the last 50,000 miles... thats 4 oil changes.

Sounds to me like you are fishing for problems...

Do what you want to, to your truck...

but blathering on and on about going insane amounts of miles between oilchanges is not the smartest thing to do on a public forum.

as I said.. it may give the wrong impression... and we dont need VQ40 grenades all over the place.

and for one thing those 4L 1-6's in the jeeps are bullet proof... an engine that responds well to abuse... IE doesnt die.

 

[tc3driver]

I also forgot to mention.....AMSOIL reccomends 25,000 miles OR 1 year. So in all actuality I will probably be changing it every 12,000 miles.

Hit 3400 miles and finally did the oil change today. The AMSOIL is supposed to help gas mileage but I never really figured the exact mileage before I put it in.....so if it does, it does. One thing I did notice, when cruising at highway speed....it runs about 200 RPM higher with the new oil in it.

;;

trying to figure out how the higher rpm is possible...
