Best Synthetic Motor Oil?!?!?!?

[wezeles]

well synthetics were bad for older engines... the only thing that i ever heard was not breaking in fully... which in new cars they say it makes no difference... i normally run a synthetic blend just because i never go more than 2,500 miles without a change... i dont need the 10,000 mile protection because i dont care what claim is made..lol i dont trust it for that long..lately ive been switching back between valvoline 60W syn blend and mobil syn blend race oil... i think the mobil stands up a tad better but its alot harder to find... eaither way best thing to do is flush your engine after every change... even if the oil looks clean thats the best way to keep it that way... even with sythetics when they break down they leave a nasty film.. thats what hurts the engine.. gotta clean it out all the way before putting the new in..

but as for all my other fluids i use synthetic... axel,trans,ps,even brake fluid now... no one every changes there brake fluid... i think thats supose to be a yearly deal in most owners manuals...

lol the other thing you will notice with synthetic oils is that it will go away faster, it finds places to leak and burn up because the molecules are smaller in size than a conventional motor oil. I was running valvoline in mine and switched to Mobil 1 for a while but then I noticed the pan started leaking and the oil level always needed to be checked because it seemed that everytime I turned around it was low.

Lmao, come on, you are going molecular on us? Tighten your damn pan bolts, lol.

hahaha shut up jasen. And yes i'm going molecular! I have a silicon/metal pan gasket that shouldn't leak at all and my pan gasket was not loose.

lmao, not yet, you can't make me shut up. lol.

out of sheer curiousity, got anything that proves this? I'm curious.

lol, well I have run synthetic on my motor and my brothers motor and both have done the same. I'm just saying for the little guys and older motors and such there is no need to run synthetic motor oil. Its not worth the money if your not using it from the first day or running a motor that you race occasionally or all the time. Just my 2cents. Feel free to call me out on this but thats just my experience.

Nah man, you do what you want, its your car. I just wanted to see proof of the molecules being smaller, cause I'm a pain like that, lol.

I personally love synthetic and will continue to run it. Just my $0.02.

[1bad83ta]

I will find you proof that the molecules are smaller. I think....lol.
Besides that why do you love it? have you seen any personal gains? Give me some proof besides the bs that all the companies feed you.

Come on, I don't want argueing here! I just wanted some hard evidence as to which oil is better. I AM GOING TO USE SYNTHETIC, you can't talk me out of it. I just want to know which synthetic to use! Oh yeah, the viscosity of 5W-30 synthetic is the same as the viscosity of 5W-30 Dino oil. . . . The S.A.E. approval certifies that. . .

[wezeles]

well as for oil to oil... a synthetic will work longer... as for the protection that all depends on what specific brand you use... the question isnt which is better its how long do you go without an oil change... and what kinda driving do you do between them... you can pay twice as much for a full synthetic over a blend... and a good 25% more for a blend over a standard oil... but if you do go thouse 7,000+ miles between oil changes... like suposedly you can with a synthetic... i guess it makes up for it in price.. it will last longer there is no questioning that... but as for protection... i think all brands claim there own your just going to have to mess with you engine and see how well it holds up... each engine is different you might have more or less carbon getting pushed back into your oil.. i would say just keep changing oils brands untill between changes your oil instead of comming out black comes out a dark brown at the worst...

[1bad83ta]

thats just the thing. I never saw a change. as for the 7000 mile stuff I would not trust my oil filter to last that long.

[wezeles]

ya thats the way i am too... besides that i like to see to make sure there isnt all of a sudden some metal shavings flying about the block... 2,500miles for me

[1bad83ta]

yep.

I agree with a lot of what MrMojo said. I would never run synthetic in a high mileage engine that has always had dino oil. High mileage engines generally suffer from loss of oil pressure and using synthetic is only going to make that worse because synthetic is a thinner blend. The latter is the reason I ran a thickness higher than recommended in my old truck at 200k miles. He is right about changing it that matters. People that get synthetic for the fact that it "lasts longer" have entirely the wrong mindset, and will probably end up making things worse by trying to go longer. I dont think ill ever go more than 3500 on an oil change synthetic or not. My car gets changed less than 3k every year because i put less than 3k on it in a year. I might push 4k in my truck since i do a lot of highway, but thats my absolute line. Clean oil is what keeps an engine running good, not how good the indegredients are.

the 350 in my last truck was still tight and had excellent compression even with 200k miles. didnt burn a drop of oil either. engine never saw a drop of synthetic, it was the religous 3k changes that kept it running strong, as well as having drivers that never beat on a cold motor, which is about the worst thing you can do to an engine.

[Orange Terror]

I believe in running synthetic oil because it protects better and no matter what mileage you put on during an oil change its going to protect better for longer because it doesn't break down as quickly.

Nick, I think most of us here agree that if you run Mobil 1 or Royal Purple you will be using a good oil. Go with one of those.

Help me out, how is synthetic a thinner blend? If it was it wouldn't have the same sae weight rating as conventional would it? Not trying to be a ****, I'm genuinely asking. But I am very skeptical. Also, other than the illeged eating of seals what does synthetic do to harm a high mileage engine? Unless I missed it in here somewhere I've only heard that its bad, not what it does to a high mileage engine.

Justin, I've been using synthetics for awhile now, and I see less wear in the filter and in the oil when I check it and drain it in every engine I've put it in. I don't listen to companies, I talked to people who have used it and tested it before I ever ran it. If I listened to the companies I'd be running the cheapest shit out there wouldn't I? lol All I'm saying guys is that synthetic oil hasn't failed me yet, so I'm not switching till it does.
