5 quarts or 5.5 quarts??

[Too Fast]

I had a 98ss I always put 5qts of 10w-40 in it and it always ran great.
I have a 2002 Ws6 now and I put 5qts of 10w-30 in it now.
I never had any problems in either car. Hell, I always thought it was 5qts. I will try putting an extra 1/2 qt in my car this weekend and see how it does.

Uh, the engine calls for 5w30 for most conditions. 10w30 maybe during hot summer months, but never 10w40 for stock, modern engines. It probably did run great, but that was shortening the engine life somewhat.

so lastnight i took my 5qt of oil ls1 to a parkinglot and attempted to see if the pump would starve but it wouldn't i even tried hard accelerating in reverse. oil pressure stayed around 60-80psi depending on rpms.

I Use 6 Quarts Of Royal Purple With A New Filter

Alot of people use 40weights around here. What do you use?

I use 0-30 AMSOIL



Or 0-20 AMSOIL

[INMY01TA]

Nothin wrong with the 0W30.

5W30 Valvoline synthetic, year 'round.

The only time I have seen my pressure drop is when I am hittin' the on-ramps hard. Long curve at max traction will sometimes have my pressure drop (think 25 MPH posted, taking it at 45 -50 MPH or better, depending on traffic, etc. Scares the shit outta passengers!).

dont use Fram oil filters, they are HORRIBLE,...if you still decide to use Fram then just save yourself the money, put a sock in a plastic bag and tape it to your oil output...............

So true. And you know how many clueless people there are out there that still swear Fram is the best and run them on there race motors. Damn shame.

Ive always put 6 quarts in with a filter change

Im trying out the Amsoil 5W-30 Full synthetic

I disagree. I run 10-40 with no issues. I ran 20/50 in my last vehicle and it lasted 300,000. It smoked when I sold it but still ran. Tell me how it would shorten the life of a engine?

Well, my opinion is it the heavier weight oil will not circulate as quickly especially when cold or cold start. That is where most engine wear occurs. I do think manufacturers go with thinner oil (5w30, 5w20) mostly for gas MPG issues. With the heavier oil, you will see higher pressures bc it resists flowing as well, robbing the engine of (a few) HP and a couple tenths MPG, since the oil pump is working harder.

What was that last vehicle you ran the 10w40 in? An LS1 vehicle?

10-40 is fine-it circulates fine-it circulates fine on a cold start.If you took two pieces of steel like two pushrods and dipped them in oil(one in 10/40 one in 5/30) and then held them up in the air-which pushrod would have a better coating of oil after 24 hours? I would like to think the one dipped into 10/40 would-not the one dipped in 5/30-therefore if you really think about the concept of a "cold start" it would begin before any oil ever started to circulate. Did you ever turn a engine over with a valve cover off? Oil is shooting through the holes before its even started.Like I said I ran 20/50 in my last vehicle and got 300,000 miles out of it before it started to smoke a bit and I totured that vehicle every day.
I now run 10/40 in my 98 Camaro LS1 with no issues. I know what GM reccomends for these cars but IMO its way too thin-especially here in Fl. If it were a new car-I would run the suggested oil for the break in period no doubt-but thats about it. My car has 70,000 miles.

Also, the 40 in any XW40 is the thickness at operating temperature, not cold start.

I knew that. Anyway, glad to here you are not having any oil issues. I prefer to run the weight that the manufacturer recomends, thats really about it. I guess if I was running sustained high RPM, I would consider a 10w40, but I don't so I won't. 10w30 won't make any difference in the FL heat, since we all know the 30 is for normal operating temps. Our owners manual says 5w is preferred for all temps, with 10w being ok for over 0 degree operation. Does not recommend any other weight, so that is what I use. Always gotta do what I'm told, LOL!!!!!!

[Sarge]

Difference between a 30 weight and a 50 weight is minuscule. What we are talking about here is film thickness. Too heavy and your not lubricating "well" in tight clearance spaces.
Wont really kill your motor per se but definetly robs horsepower and does shorten life expectancy of bearings/rings...

Do you still run a .060 plug gap?

Why you ask. You gonna diss me bc I still have my OE plugs at 66k?
