Hi all

I'm noticing a small drop on oil. This worries me as IMO i should be drinking oil as I am not thrashing the engine.

What does anyone think? What have you read? Is there a problem with LS1 and oil levels?

The Ls1 is the worst engine I know of for dil consumption.
You could ceck
The vent line from the valve cover to manifold for oil
pcv valve to manifold for oli
or pull the throttle body and do a wipe of the inside .
If you do alot of engine braking, that increases the engine vacuum which pulls oil pass the intake valve seals.

Indeed... the LS1 consumes oil like crazy for some reason. Where it goes? I have no clue. I just know that when I change mine every 3k miles it's down about 1/2-3/4 of a qt. Nothing to be concerned about... just the nature of our beasts.

hmm, still not worked it out.

My 99 LS1 in the HSV is not drinking much at all.

Brian, nice car by the way.

Thanks Jagsy!

This may be a stupid question, but what the heck is HSV?

A HSV is my new wheels - its an Auusi supersaloon. But it uses the same LS1 - with all the smog restricting stuff removed so its punching 343HP and 360lb ft torque.

Have a look in the picture posting forum and "my new wheels" half way down the page, there are a lot on links lower down the thread.

What do you think?

D'OH! I can't believe that I didn't know that! I'm a fan of Holden and would love to get my hands on one of their "grocery getters" someday...lol I'm jealous!

Mine doesn't use oil and Jagsy, you were thrashing that HSV when I went in it . LOL!

Jagsy · **Posted:** Sun Sep 21, 2003 5:37 pm

Lus1fer - are toy back already!!!! Hope you had a good time.

Grocery getter - please I'm a professional taxi driver. Next fair please mate.

Well I've done 5k miles snice that last oil change. It's dropped a teeny bit, nothing to worry about. But the colour has changed, time for a chnage.

LuS1fer · **Posted:** Sun Sep 21, 2003 8:32 pm

That reminds me, mine needs doing too.

My LS1 doesnÃ‚Â´t need oil - i got more than 100.000 kilometers on it...

I remember reading that the LS1 actually has a recall on some engines. Some do really well on oil, and others just drink oil like a private returning from the field that tries to drink all the alcohol in the city in one night. Anyways, mine is one of the ones that like oil. I change my oil about every 2000 miles and I use Mobil 1 10W-30 Synthetic, and I usually have to add an entire quart before my next oil change. I check all the time for oil leaks... cause I thought there is no way my engine could use that much oil... but time and time again... its the same process... and my engine always checks out fine at the shop.

Try subbing a quart of 15w50 mobli one in the mix. It help me out a lot.

hocheehoba · **Posted:** Tue Sep 23, 2003 4:41 pm

I always put 6 quarts in when I change my oil. So then what you are saying is I should use five 10W-30 and one 15W-50? Ok. Should I do this every oil change?

Garry · **Posted:** Tue Sep 23, 2003 5:20 pm

On another board, they recommended against mixing oils with different numbers ... but then, that was for 2l 4cyl Toyota engines

hocheehoba · **Posted:** Tue Sep 23, 2003 5:24 pm

Ok, Mix dont Mix. Damn. This is like being married. Damned if you do, damned if you dont.

Roy · **Posted:** Wed Sep 24, 2003 2:18 pm

It eeorks great for me . But then I don't drive like the normal driver would. :lol:

Hey Roy,

Would like to me to take a sponge and some soapy water to your car? Would gladly do so. Just let me know.

From what I been hearing. LT1's have a little leak coming from the back of the manifold (by windshield wipers) that is suppose to be normal because of the small thin gasket versus the compression . LS1's might be the same?!?!?!? As for oils I dont think synthetic is the way to go. We normally drive with the RPM around 1500-2500. Synthetic is usless to us V-8 boyz and gurlz. Stay with regular oil because we dont have high revving machines. By the way the difference between the oils id that synthetic soaks in the heads versus lubrication. So, by the time you drag race a few time your oils levels will decrease and so will the viscosity of your oil which equals no protection for your motor. :wink:

... I spun my cranck bearing a while back!! also look at you oil containers, the later the alphabet code the newer the oil/production. i.e. SG/SE/SJ

Keep in mind that some engine builders recommend that only synthetic oil be used in their engines. Callaway would not honor his warranties if anything other than Mobile 1 was used. This was a while back so I don't know if is still like that. BTW, I found this out from talking to him back in '97. He has a shop in Leingarten, near Heilbronn. He is usally there around the time of year that Lemans is going on. (He races there.)
