Just a Oil question
 

I just bought a 2003 mach 1 with 50,000kms and the guy who owned first tryed telling me I should not use synthetic only normal oil. is this guy crazy or what I use mobile 1 even in my minivan as well as all other cars, has anybody heard anything that would be a bad idea with this?

Since I just happened to be browsing through the owners manual on the 5.0L the other night (yeah...geek...go ahead and say it :rolleyes:), I remember reading that it recommends both synthetic and super premium motor oil. My other car has a 3.5 HO with 288,000 kms (can I mention it in this forum if its a mopar? :) ) and I've always used regular oil.

I'd be curious to hear what you guys have experienced...synthentic versus real oil.

it all depends on preference really it's not a huge deal. personally i run a full synthetic unless i'm breaking in an engine.. im posting a quick reference for you.

quick notes: might as well stick with synthetic. :tup

lol i ramble on bout my mitsu all the time i'm sure it's cool :wink:

So we're good as long as its not Chevy :D

u can use synthetic but once u start using synthetic oil u should stay with it dont change from regular oil back to synthetic all the time. but i say synthetic is better i use it in all my cars.

I swear by syn

Your good to use it!:tup

I have synthetic in my Stang..

The wife's Foci and the Dak will be getting it in the spring. I use Royal Purple in the Stang....

royal purple for the win!

Synthetic oil is meant for extended drain intervals. If your gonna change it at 5000k don't bother with the added cost and go with conventional. And there is no harm in going back and forth from syth to Dino oil. That is nothing but a fairy tale. Red line is good AMSOIL and royal purple. Mobil 1 is not a real synthetic as it uses hydrocracked Dino oil as base stock. Join the bob is the oil guy forum. There is some enlightening info there.

My preference goes like this
Amsoil
RP
Mobil 1

Of coarse each to their own

I use Mobil 1. As long as you buy brand name oil and change it when needed you will be fine. Synthetic doesn't hurt but I don't believe in using it to extend the distance between oil changes. It still gets dirty no matter what it is.

I used Castrol Synthetic Blend 5w-30w, mind you I don't have a Gt.

yea but i bet that 4.0 is in better shape than most GTs :tup

I totally disagree with there being no harm in going back and forth from Synthetic to regualr engine oil, and actually to take that it a step further, I would not even switch brands of oils. You need to understand that every oil company uses different chemicals, and different processes, to refine their oil, and in some specific cases, these chemicals cannot be mixed, and if they are mixed, even in the slightest, it can cause a major reaction in the viscosity of the oil, and possibly result in damage to your engine! Also, do not, I repeat, DO NOT use additives. Here is a link I posted a couple years ago on this forum, and it talks about engine oils, and aditives.

Oh yeah, I forgot, I use Mobil 1 synthetic, and would suggest either that, or Amsoil. Both very good engine oils.

Essentially it is just like it came off the show room floor, with about $10,000.00 other goodies on it. For a sleeper she purrs along pretty good.

I tend to agree with you regarding not switching brands. But sometimes you are let with no choice. For example from the time I got the 05 until early last year I was using Quaker State 5w-30w High RPM Oil as this was the oil that was recommended in Mustangs and Fast Fords. In the fall of 2009 Quaker State for whatever reason discontinued the High RPM Oil so I had no choice but to switch to a similar product by Castrol. I have used castrol before in my other mustangs and have no problem with the Castrol product. I would rather have had the Quaker State High RPM Oil because I am not a fan of switching oils, unfortuanately, I along with probably several thousand others was left with no choice.:?

I have the oil changed at the dealership (I know lol ) and they use 5W50 Mobil 1 Synthetic and I have no problems with their selection. I generally put no more than 500-800 miles on per year so the oil is in good/great shape when dumped. With fuel/oil prices going up I wonder what the oil change will cost me this year. Last year for 7 liters and a filter the bill came to 112.00. I will let you know in 2 months.

Wonder what the price is at Kaddafi Oil and Lube?

I would say that there are some oils that are better than others, and in my opinion synthetic is the way to go, but all-in-all if your changing your oil regularly, and not going over the recommended mileage, that is the most important thing, and your engine will treat you as good as you treat it.:chacha:

Bwah to funny:lol

I like synthetic myself.
If my memory was better I would tell you where to find an article about blended synthetic oil and the lawsuit.The short version is that many synthetic oils are actually blended but you wont know untol you check the code on the back.

I'll be running royal purple after I scrap my break in oil.

Off topic: BTW.. Crafty, what local are you? Didn't realize you were a fire fighter.

The biggest thing (of coarse) is the regular change. I use syn and change it once a year in Apr. Oh yeah just around the corner
