2003 Lightning Guzzling Oil???
 

I have a 2003 Lightning and I am using AMSOIL 5W-30 100% Synthetic. I put in 6 Qts when I changed the oil a couple of months ago and it burned 1 qt. of oil in about 3,000 miles. I was just wondering if this was normal. Thanks

First, welcome to FTE!!!

Have you recently bought the truck, and just started using Amsoil in it? 1 quart in 3000 miles would be considered "normal" oil consumption. But, if I
were you, I would try running a API certified oil, instead of the Amsoil.

Thanks!


I am the 1 and only owner of the truck. Im using the Amsoil because it's the best oil money can buy IMO.....What kind of oil are you recomending?

Here's the site....https://www.amsoil.com/storefront/asl.aspx

I'm very familiar with the Amsoil site, you can't believe most of the stuff they have posted on it!!!

Basically anything but Amsoil is API certified, Mobil 1, Royal Purple, Castrol, Chevron, Valvoline, etc. ....

What oil were you using before the Amsoil? Any consumption problems with it?

I have no clue! I was soo dumb myself I was taking it to a local goodyear auto shop. But in the Owner's Manual it says to use 5W-20 isnt that too thin?

use what the book says 5w-20 wprks the best

I'm also running the Amsoil 5w30 and have no problems with it. The truck only sees about 1500-2500 miles/year though. There is no need to get 5w20. The only reason they changed it was to get an extra .1 mpg out of the fleet. The engines are the same as they were previously when 5w30 was recommended.

It is common for the Lightning to blow oil backwards through the PCV system into the intake ducting. If yours is doing that it will definitely consume some oil.

BTW, certified or not, there is nothing wrong with Amsoil.

Only way over priced (due to the pyramid marketing structure), and all oil products but 2 are NOT API certified......

Amsoil must think the API certification is important, because they recommend their only 2 API certified oil products for vehicle manufacturer warranty reasons. They also try to deceive you into believing that ALL their oil products are API certified.......they even have API CJ-4 on the bottle label
for their DEO diesel oil, and it IS NOT API certified at all!!!

So, why would you buy products at such outrageous prices from a company like this????

Thanks for the info! Well it's not that big of a problem it just lowered alittle and it made me curious but Amsoil 5W-30 is good stuff....Plus I cant go wrong cuz I am sponsored by them anyways...:-jammin

You're right, $6/qt is way too much considering that Redline and Royal Purple cost $2-3 more than that if you can get a deal on them. $6 for a quart of full synthetic doesn't sound too bad to me when you have to search to find a bottle of petroleum oil for under $2.

Warranty reasons are probably the only reasons they bothered certifying those two products. Those two products probably account for 75% of their automotive sales. If I bought a new car and knew the dealer would screw me if I had an engine problem because my oil of choice was not certified I would change oils to better insure myself against that happening. Instead of losing those customers, they certified their most popular products. That certainly sounds like a mystery to me.

You mean like how you are trying to deceive us by printing lies and half truths about a reputable company? None of their non-certified products say or imply that they are certified. Saying API CJ-4 on the bottle means it meets that specification and has nothing to do with certification. The ONLY thing that identifies an oil as certified is using one of the two API certification labels on the bottle. But I'm sure since you are such an authority on this topic you already knew that and just chose not to mention it so you could twist your argument to slander Amsoil.

A company like what?

Do you work for one of their competitors? It's obvious that you have some sort of personal vendetta against Amsoil. That being the case I'm going to bow out of this conversation. It isn't worth the effort with someone that seeks to do nothing but spread fertilizer.

Is that a promise??????? :-X22

How can they say it meets CJ-4, when they don't have the testing facilities to test it??????

Just like the ATF that they claim meets Dexron VI , Mercon V, Mercon SP, and ATF+4 specifications!!!

Obviously they don't understand that the specifications for the four different ATFs DO NOT OVERLAP!!!!!!
