Cool, cause right now it's colder than a witches tit and I don't want to be fooling with changing the oil myself right now.

holy cow its that bad to use synthetic eh...
even if you use the thicker blend? or is there no thicker blend?
I heard a lot of people using Royal Purple on their lancers...
so those people will blow their motors sooner than
those who use regular oil?

 

There is absolutley NO TOLERANCE in the bearings in an EVO for regular oil..if you want knocking within 200-300 miles, use the regular..synthetic sticks to everything and doesn't break down..its common sense

 

This is in the regular Lancer forums, ace.

If someone has a compelling, conclusive, logical, even scientific reason for claiming synthetic oil as the cause of their engine failure I'd love to see it. I've yet to see anything remotely convincing.

 

I go back and forth on my tacoma all the time ($$ depending). I've never had a problem other than dorks who can't tighten an oil pan bolt, I guess that's irrelevant through

 

thanks for clearing up my mistake, ace

 

I would like to see that too. I have ran synthetic oil in my Lancer since the first oil change. Now with 40,000 plus miles on it, I have no problems. I use synthetic in my wife's car, and after 52,000 miles, there has not been a problem.

 

In the name of all that is holy, this thread is almost 2.5 years old!!!

Anyway, I have to call BS on this one too. And really a very late medal to TEXSRT4. All these post saying synthetics are too thin... strange as it may seem, there are several grades.

Now as DF said, viscosity is viscosity. There's no magic between synths and normal viscosity-wise. The numbers tell the story.

As i recall, non-synths actually contain a broader range of viscosity values which average to the overall viscosity....

If it's the oil's fault, i would love to see it. We'll soon be putting lard into our cars cos these new-fangled oils are just too darn thin!!

 

RRM told me NEVER to run synth. in a turbo'd Lancer. So i'm not even running a blend. I think it's 5/10w30/50 in mine. No problems being boosted or n/a.

 

I think that has to do with the effect of heat on synthetic oil, but I'm not too sure. For the average person it makes no difference, I run synthetic oil currently just cause I wanted to.

 

RRM was one of the sources of this rumor when Kontra spun a rod some years back. The viscosity rating is what determines the oil's "thickness", not whether it came from a dynosaur or a lab. Synthetics actually tend to degrade less (and therefore lubricate better than dino oil) under extreme heat.

 

I have been running Synthetic in my Lancer since day one with no problem at all. Look at my sig for how my engin is set up!
Synthetic oil is a good choice if you have a vehicle with a high performance engine (in fact synthetic is required for many of these engines). It is also a good choice if your vehicle is operated in extremely cold climates. It has higher resistance to breakdown caused by heat and it flows better in extreme cold. Unfortunately for the synthetic oil industry there is virtually no advantage to using synthetic oil in a non-high performance engine that is operated in moderate climates. You probably could go a bit longer between oil changes with a synthetic, i.e. following the normal service schedule even if you fall into the severe service category, but I wouldn't advise this. In short, synthetic may give you the peace of mind of knowing that you are using an oil that is far better than necessary for your vehicle, but it won't reduce wear or extend the life of the engine.

 

I've been running mobil 1 synthetic on my car for about 5,000 miles now with no problems to report. When i went in for my 15,000 maintenance an oil change comes included and I asked them if synthetic was bad and they said absolutely not and put that in instead (for an extra 20 of course). The mitsu tech was confident that it would be fine for the car (yeah i know any tech can be wrong but come on, this guy really seemed to know his stuff). so if the dealership will put it in, logic would dictate it is ok for the car. i know this doesn't prove anything, but maybe it helps

 

Synthetic is fine. Why we have this debate after all these years, I don't know...

 

True. There are now so many urban legends about motor oil they should give it a show on the Discovery Channel.
