Ok Ive got a 90 GS with like 250k on it. The previous owner never changed the oil for like a damn year. I use it to deliver pizzas so im just tryin to keep it alive as long and as cheap as possible. I'm using about a quart a day when I deliver, and I put about 200 miles a day on it, 45% of which are full throttle on back roads. It has lasted me longer than expected like this, so I cold really care less if it blew tomarrow.About 6000 miles ago it started to knock, so I went and bought some $26 rod bearings, installed them and its been quit since.
Is there any additives (Prolong, Dura Lube, ect) that I could use that my prolong this tired b18s life? I run 20W50 in the summer and the occasional bottle of no smoke

 

Auto-RX its all-natural and well worth the time http://auto-rx.com/

If you want something you get get at the local AutoZone get Nuetra


Also I SWEAR by AUTO RX I used it in my moms Montero, my dads Mercedes, my Integra has it in there now and my dads beat Corolla.

 

Also just read over on Bobistheoilguy.com/forum for other good additives.

 

Deliver me some pizza! j/k

Probably wanna try sea foam.
More like a flush rather than an additive.
But it helps.

 

if you sea foam you prolly will lose some compression due to the carbon .

no no no

don't put seafoam in your motor; all those cabon deposits are what's keeping your motor together
seriously, sea foam is good for newer motors that are in relatively good condition.

just use the additives mentione above or a number of others that will keep things thick and quiet in your motor, allowing it to die a peaceful death.
oh and death will come cause additives suck
