Regular or Synthetic Motor oil?

What is better for vehicles?


I hear Synthetic is better, but more expenseRegular or Synthetic Motor oil?
Synthetic.... keeps the engine clean (engines raised on it are usually spotless) this is the reason why vw, toyota... etc have specified syn for they're sludge prone engines (not all of em are prone to it) it pumps quicker in the cold so less startup wear, likes to stick better to the metal (some syns) and due to it having natural volume index improvers and pour point depressants, they are very shear resistent (go out of grade harder) and they will stand up to higher heat, longer.....





But don't count conventional out.... most oils today (like pennzoils) are group II+, its just short of being a fully hydrocracked synthetic.


People can get many a mile out of conventional as well.





Hydrocracked syns were fought about between castrol and mobil.... mobil being a true pao synthetic, castrol selling its hydrocracked oil as a syn.... at synthetic prices.... when it should cost alot less. Well they won.


Pennzoil platinum is another true synthetic to look at.








Don't beleive the ';you can't switch back'; bull...... you can and you need no engine flushes to change over either...., just drain the old oil (change the filter of course) and filler up with synthetic and drive.... simple as that.Regular or Synthetic Motor oil?
I like the synthetic's no real reason. My dad who is pretty car knowledgible tells me as long as your doing them on time it won't matter
yes it is more cost for synthetic oil and it is better. make sure that u get an oil flush though your engine. u just cant switch over from regular oil and if u start using synthetic u must stay using it.
No Question. Synthetic.

You can by a 5 quart jug of Syntech, at Walmart for 12.00.
my only comment is that you do not need to get engine flushed and yes you can switch from one to another. You can use synthetic for one oil change and then conventional the next they are completely compatible. I would just recommend that if you have a lot of miles on your car and hence it is leaking you don't use synthetic. It will not cause leaks but it will find them very fast and leak out easier than conventional oil. It is by far the best oil to use but do you really need it or will you benefit from it? Probably not. Unless your car calls for it from the manufacturer there is really no reason to use it. I hear people say all the time that '; I have 200k miles and all I use is synthetic';. Well I've owned and operated 3 quick lube centers for 20+ years and believe me I have seen more vehicles with 200k mile on them with conventional oils than synthetic. Simply put just change your oil on time and you should have no problems with either oil you choose.
Synthetic is good BUT way over priced for the term you get

Synthetic oil has smaller molecules and is increadibly good at redusing wear. HOWEVER, it should not be used in the initial break-in period becase it will prevent the engine from actually ';breaking-in'; due to its lack of friction. Also, it should not be used in a high milge ehical that has been running on conventional oil becausethe smaller-moleculed synhetic will more easily leak through worn seals
