I run Amsoil in all my cars . I can go up to twenty five thousand miles between complete change out . Still do a filter and top off every five thousand . Amsoil now has their own oil filters now that are a little pricey , but don't have to change them until you do the complete change out . Amsoil is $7.00-8.00 a quart . But in the long run it works out in my favor anyway with the benefits you get (no crude) . And not putting my hard earned money overseas in Saudi Arabias pocket .

 

I know switching to synthetic will get you better gas mileage also...I will soon be switching to synthetic also and I've been told Mobil One is good for the price...One of the more common brands is Royal Purple however, I was told that it costs more "because of the name" and Mobil One is a better way to go.

 

And not putting my hard earned money overseas in Saudi Arabias pocket .

your still buying gas right :4-dontknow:

 

Don't have a choice there !

 

so would it be safe for my HEMI to switch???

 

42000 Miles is a little late to change now. Your piston rings will allow it to burn oil since synthetic is extremely thin. Just keep an eye on your oil level. Also Mobil 1 is hands down the best synthetic besides AMSOil. Good luck with the switch.

Oh yes you are right Smitty. The viscosity is the same. The reason people think synthetic is thinner is because it leaks out where regular oil does not always leak. This is because in synthetic lubricants the molecules are all equal in size (makes it flow smoother) and do not build up and cling together like fossil oil does, and clog up the actual leak in the engine. Synthetics are the way to go if you can run it and not leak it all out on the ground.

This is what im talking about.

 

Go with Valvoline Syntec or Penzoil Platinum (maybe ever Quaker Stake Torque Power)! These will be the best 3 you can buy. I use the Platinum in all my cars and it works great. If you didnt buy new and have no warranty, go with the Syntec as they Garanty you motor for 300,000 miles.

 

I spoke to the guys at a local shop in the phoenix area and they said they wouldn't recommend changing. They said it would start leaking all over the place because the synthetic is much thinner. I haven't heard of any real proof of this though. I'd also like to start using AMSOIL in mine, it has 33k miles. it's an 04.

 

33k miles is fine. You won't have a problem. Where about in Phoenix are you? I am in the Mesa area... PM me and we can meet up somewhere and BS a while.

 

will be in Phoenix 10/9-10/10 to race and do the gtg poker run cruise (10/10)...we should all meet up...I know alot of others will.. I use Amsoil myself.. 1 guess what the 3-4 fastest 1/4 na hemi qc's use, it isn't just coincidence. And runnin my 13.1's at the track with over 160k miles on her is a testament in itself..

 

There is a possibilty of leaks just dew to the synthetic cleans out what the conventional could have made a seal with but the synthetic will seal it back it wont be this hugh leak if it even leaks at all.

 

So overall is it a yay or nay on this beginning question?? Cuz im curios cuz my 06 is gettin ready to hit 50,000 miles

 

...synthetics are always better..especially as miles begin to rack up..

 

i went to it.

 

Thanks everyone for their input. Means alot!!

 

I have over 160k on my 95 RCLB 4X4 with a 318. I switch back and forth between the synthetic and regular oils with no leaks. I run synthetic in the winter mostly. It get cold here in MI. In my Daytona I mostly run Mobil One, but it only has 18k on it...till tomorrow when it will head out to Colorado Springs, CO, with the family and me! First time out west, It's been to Florida twice.

 

Know what is great and an amazing deal. go with Valvoline syn-blend. this way if your rings are going you will not lose all your oil out your tail-pipe. about 5.00 a quart. also not 100% man made or to thin of a product

 

i talk to the guy at my local DYNO shop, asked him about what he stocks as far as oil, he told me Mobil one, i asked about Royal Purple & he said it wasn't worth it, he mentioned that he carries another synthetic oil as well, but, i didn't write it down. i'm going with Mobile one http://www.thedynoshop.com/

 

I changed over to synthetic and I will never go back. I actually noticed a difference when I switched. I dont know if it was just in my head, but i really think i made the truck run better. Also I have a Oil Pressure guage in my truck and that moved a lot smoother when switching over to synthetic. also any engine knocking i had before all went away with the synthetic switch

I have the Castrol Synthetic in my truck. Just a buffer till i get my hands on some Amsoil haha

 

My next oil change I will be going to Amsoil 25K mile synthetic.

 

Amsoil, and mobile1 Are the two best fully synthetic oils that are available. I run Amsoil lubricants in all my stuff. In my Harley when I switched from regular oil to synthetic oil it lowered the temperature of the oil 30 degrees. That is a huge difference on an air cooled v-twin. I will never use anything but Amsoil from here on out. Most importantly, find a brand, and type of oil and stick with it. Do not change around all the time. just my $0.02 worth.

 

Oh yes you are right Smitty. The viscosity is the same. The reason people think synthetic is thinner is because it leaks out where regular oil does not always leak. This is because in synthetic lubricants the molecules are all equal in size (makes it flow smoother) and do not build up and cling together like fossil oil does, and clog up the actual leak in the engine. Synthetics are the way to go if you can run it and not leak it all out on the ground.

 

The viscosity change shouldn't cause any leaks at that low of miles. I just got my '03 with 40K and went straight to mobile 1 truck/suv synthetic. No leaks.

 

royal purple is the best

 

I have used Mobil 1 oil for twenty years in all of my cars and trucks. As of the mileage issue I have a Toyota T-100 it had over 80k on the clock when I got it used in 1997 the truck is a 1995 I still drive it everyday to work on a 75 mile round trip the truck has 320,117 miles on it. NO leaks, we also have a 2001 chevy blazer 4x4, a 2005 Dodge Ram 5.7 hemi, and a 2007 Dodge Nitro, all use Mobil 1 no problems or leaks, I think if anyone exprienced any leaks from changing to fake oil motor was already leaking or was about to leak

 

Hey, we should all meet up sometime and bs, i'm from the queen creek area...and I would personally stay away from quaker state and penzoil, I have been involved in import racing as well as drag racing and they all swear by mobil one, from what I have seen...it's the best.

 

Is there a major chain that carries AmsOil or do you have to get it from a independent seller??
