Why synthetic?

synthetic is going to be better because the man made hydro-carbons are stronger and will take longer to break down into what later become engine sludge. conventional oil is good, but say you get busy have no money etc. the conventional WILL start to break down and leave a little deposits her and there. if you use synthetic you can easily go 5000 miles and still have decent oil. the oil filter is also a large contributing factor to the life of the oil, and your engine. any questions you can just PM me

 

Ok so my truck has almost 9,000 miles on it. I do not know what kind of oil is in it because the dealership takes care of that for 2 years for free. I'm guessing they put conventional oil in it.

Should I tell them to switch it to synthetic? Do I need to do anything else for it to run properly? just change the oil and filter?

Out of curiosity, how often do most of you get your oil changed? I tend to think I should do it more often than the dealership says it should be done.

 

my dealer gave me 2yrs for free but they used bottom shelf quaker state. they refused to use synthetic for free so i just started doing it myself

 

Because when you tell people you use synthetic it sounds like you've done some sort of upgrade.

 

I would just do your own oil changes and use Mobile 1 or castrol. the dealer ship tends to cut corners to save them money, and if you do you get to know your truck a little more and you know its done right.....or wrong. and to be honest, coventional oil is better for the engine break in because it kinda coats everything better but later on switch on over to synthetic

 

they usually get the bottom shelf stuff for mega cheap and they use that so they wont spend much of there money.....it is a business, and business aint fair or pretty

 

That's the lamest excuse I've ever heard. There are far more, and better reasons to use synthetic than extended intervals.

 

x2 i accually change my synthetic every 3k for good measure haha but im paranoid like that.

 

Mobil1 ... like breast milk. bbbrrreeeaaaassstt mmmiiiilllllkkkkkk!lol

 

That's what us Canadians do. Every 5000kms.

Ever try telling the wife that going past 5000kms is fine running synthetic?
Jesus, I'd have a better time giving a cat a bath in burning lava.

 

i'll tell you why the fuck not
at 120k his gaskets are old, mostlikely never been changed, synthetic has far more cleaning agents in it than dino oil, will make those already "close to leaking" gaskets swell and leak, he'll freak out because he'll notice oil leaks...

 

120000 Km.

Wanna keep playing this game?

Second, up in Canada we change our oil every 5000km or roughly 3000miles.

I doubt he has much build up in his engine.



That's why.

 

Flew helos in the Army, now I fly them in the Coast Guard. They run synthetic oils in gear boxes, transmissions, and engines. From -20 deg F. in Fairbanks, Alaska to +130 deg F. in Iraq, the synthetic oils always took the punishment and kept me in the air. If synthetic is good enough for aircraft, it's good enough for my truck.

 

what game? your tunnel vision game?

OP never mentioned KM, he said 120k, used lbs and miles for his other numbers, it's only common sense that he wasn't saying KM but 120k miles...

 

Alright, calm down. I'm not trying to bash the shit out of you.

Dude lives in British Columbia.


Canada.

Guess what we use for measurement up here. Metric, that means Kilometers.

For some reason though we all use lbs and feet though. At least anyone over the age of 20 does.

But I could be perfectly wrong mind you.

 

Synthetic oils are really just "dino" that has been selected for molecule size.
The uniformity of the hydrocarbon molecule allows the oil to lubricate more consistantly.
I was told to think of oil molecules as ball bearings. In conventional oil the "ball bearings" are many different sizes, the largest ones take all of the load, this creates wear and reduces component life. The are also tons of other compounds like paraffinic wax and sulfur compounds that under extreme conditions (which is any conditions found inside an engine) will "coke out" and become sludge/engine deposits.
Synthetic oils have very uniform, selected molecule size spreading the load across a uniform layer of "ball bearings" which reduces wear. They also contain very few of the paraffinic wax and sulfur compounds which allows longer service intervals.
Ironically, one of the best sources for the refining stock for synthetics is actually used motor oil. We have already removed a large portion of the paraffin and sulfur, by allowing it to coat our engines with sludge. We have also broken down the largest, least desirable molecules in the process of allowing it to prematurely wear our engine components.

 

I decided to switch to synthetic as synthetic oils maintain there consistency better over time. I only drive about 3k miles a year, so I only need to do an annual oil change this way.

 

split the difference..... use semi synthetic

 

The half breed of the oil world?

The Tiger Woods if you will?

Next think you know a Ford has it's crankshaft in your Trucks intake manifold.

 

thats complete bull shit........
