Oil Change Time

[Need4Camaro]

128K miles... going on a trip, car needs one BAD. Should I go with a high milage formula, synthetic, or regular? Also should I add Lucas Oil Stabalizer?

If your car has never had synthetic in it, I would not start now. Just keep using a name brand oil. I have been using Valvoline High Milage oil since my car had about 80,000 on it. 36,000 miles later, I have had no problems.
Although your car has high milage, I would not add anything to your oil.
Just my 2 cents.

I heard Wal Mart oil is realllyy good oil.

Synthetic, definitely. But once you start w/synth you can't stop. If not that use a high mileage.

regular oil is fine. What is really important is a good quality oil filter.

If you have a high mileage car I WOULD NOT switch to synth. it is thinner oil and will find a way to leak...mine did. I started w/syth at 85K and it leaked like a b%tch. once i switched back to normal oil it was all good. I used high mileage oil and i felt it helped slow an oil pan leak and my wife's car stopped blowing blue smoke...

If synthetics start a leak can Lucas fix it?

...u switched BACK to regular???? herd that was bad...but not sure why....someone fill us in plz

ahhhhh

ok you can go from oil to syn to oil YOU JUST CAN"T MIX THEM , now some of the new syn say they can be mixed with reg oil, those are ok to mix.

now i used the quacker high milage FULL SYN or quacker for high HP motors FULL SYN and NEVER HAD ONE PROBLEM WITH THEM leaking.

[BLLDOGG]

What? That is a huge myth. You're not supposed to mix the weights. Synthetic bonds just fine with dino.

I have always used the wal-mart 4.3 V6 oilfilter on my 3.8, model ST3980. I had a cold lifter clacking noise about 3 months ago (started) used Mobil 1 10-30 and Mobil 5-30 and it still made noise when you first started the car and it had been sitting for about 1 hour or more...two days ago I was due for a change and I bought the wal-mart supertech 10-30 full synthetic and it stopped making noise. The ST Full synthetic is thinner than M1...even the M1 5-30.

On the 3.4 I used to own, bought it with about 120k on it and ran mobil 1 10-30 on it for about another 15 grand until I sold it. It did not leak or anything...In fact it smoked a little less on cold start ups with M1 than it did when I first bought it and it had dino in it.

These are just my findings.

With high mileage, I'd stay away from synthetic if you haven't been using it all along. I recommend Castrol, but whatever you've been using will be great. If Pennzoil or Valvoline or one of the others with high mileage formula, that will be great too.

And you can mix the weights of oil guys. LS1 guys have been doing it since '97. When yu need a mixture a little heavier than 5-30 but not 10-30....4 qts of 5-30 and one of 10-30 is alot of LS1 guys method. It is fine as well.

Just grab the stuff you've been using all along, or get their high mileage stuff, this is easy.

i switched my 97 to Mobil 1 syn with a K&N oil filter, at 81,000, right after i bought her. no problems here. she now has 128,000 and the only leak(drip) is around the drain plug. and that is only because i have to fight it to get it out. 3 inch exhaust from the heasders back, make for a tight fit.
