1999 SL1
Default Use Heavier Oil For Older Cars??

My Car: 1999 Saturn SL1
Miles: 260K
Oil usage: 1 Quart per 800 miles
Oil weight according to Manual: 5W-30
I am the original owner.


I have always used the 5W-30. A mechanic told me that he uses heavier oil for older cars.

Your opinions please!!

Thank you for your help.

Keep using the 5w-30. That's what the engine was designed for, and it seems to have done you well to this point.

^ Yep.

Use a quality oil, not high mileage.

Clean or replace the PCV Valve, or put in a fixed orifice one.

As a very general rule mechanics are ignorant when it comes to oil. Save the xw-40/50 for racing and whatnot, not general daily driving.

Default Re: Use Heavier Oil For Older Cars??

mobil 1 start early though using synthetics on older cars can supposedly dislodge sludge and destroy your engine, so if you start synthetic under 150k you're probably good, i've been using synthetic since 60k and at 145 k now and it runs like new..., other wise pennzoil high mileage is actually good for dino I wouldnt use any other high mileage dino stuff, but probably just start at a good clean dino at 260k, high mileage is good if you burn alot of oil.

1 quart per 800 miles is a ton of oil.. I would actually recommend pennzoil high mileage 5w30 i used that on at saturn that burned alot of oil and it calmed it down ALOT. unless you wanna get new piston rings installed

Default Re: Use Heavier Oil For Older Cars??

^^^ is 100% myth.

I switched to synthetic at 185k in my SL2 (mostly due to the oil rebates -- see the sticky thread I started in the general forum to get good oil cheap).

All my cars have been switched over at anywhere to 100 - 200k miles. No issues at all, unless cleaning up the varnish inside of the engine is a bad thing.

Default Re: Use Heavier Oil For Older Cars??

I've used Amsoil on my previous vehicles, on new and rebuilt engines, and have had good results with it.

I've talked to many mechanic's about using a heavier viscosity oil on a older worn engines.
Most told me it will slow the burning a bit.
But you do have the trade off of more wear during start ups, and harder starting in colder climates.

As for switching from Dino to Synthetic on a 2002 SL1.........

I saw problems with Seals, Head & Oil Pan gaskets that failed.
After I did the switch to Amsoil.
But I can attribute these failures too the fact the SL1 was poorly maintained before I became it's third owner.

jcumens,
Your engine qualifies for a MMO Piston Soak.
wolfman has the procedure on the forum.

Then switch to a Synthetic oil, or stay with Dino oil.
But change your oil & filter every 3K faithfully.

I'm not sure there is any concern using a 10W30 VS 5W30 in temperatures above freezing. There is maybe some argument that the 10W30 has fewer viscosity improvers that aren't really needed in warmer temperatures anyway. How excessively high could the viscosity be at 0C or above? I'm sure at -20C or something lower, there might be a concern. I'm thinking about using Rotella 10W30 as my next change, for the summer. I haven't found a factual reason not to.

I can tell the difference in the way the 10w-30 flows, even at 75 Degrees when pouring it from a bottle. At 30 or so, it really becomes apparent.

I used 10w-30 for a long while while living in CA, but switched to 5w-30 at some point during that time. Why have any extra wear if it can be avoided?

There are 6 different Rotella oils and they are far from the same formulas.

I haven't decided if I will just use the conventional Rotella T 10W30 or the T5 Synthetic blend. Any reason why one or the other would be any extra wear over say Pennzoil 5W30 yellow bottle, for the summer months?

Those grade numbers represent a range of viscosities. With any non-pao oil formula the base oil is the lighter weight oil and VI improvers are added to make the oil pass the higher grade number. Now what do you think happens to film strength when they get excessively hot? All oil tis to thick to flow correctly until warmed up and it takes longer to get the 10w-30 to flow as compared to the 5w-30. A full synthetic is produced starting with the higher grade number base stock and then additives are used to produce the lower one. I most cases the pao base oil has a sufficiently high VI index that minimal additives are required to produce any given multigrade oil.

And as such a 10w conventional would have less VI than a 5W. At well above freezing temps that most experience in the summer, the cold start viscosity at 50 or 60+ degrees is probably more influenced by the oil type than the base weight.

As for the hot temp, once again it's a swag. The OEM recommendations are for the original tolerances the engine was built to, not the worn tolerances that most cars now have unless they have a fresh rebuild.

Quite a few people run heavier weight oils without any known issues. As for the wear claims, without a lot of data it's just claims. Drive cycles and conditions will probably be the best guide to overall wear. Some will use the best available oils and spend more money avoiding a rebuild. Some will go cheap on oil and pay the extra money in earlier rebuilds.


It's your car.... pick your poison.

For anyone who actually cares go look up your favorite brands of oil and then look at the available grades in each product line. Each product line has a different base oil. You will find some that have 0w-30, 5w-30, and 10w-30 in a single product line but not many.

1999 Saturn SC2 4 speed automatic. My owner's manual recommends 10W-40. I've always been a Valvoline guy. Around 185k I noticed puffs of smoke coming out of my tailpipe. I never had to add oil prior to this between oil changes. I mentioned this to my mechanic and was asked how often I had to replace oil? I told him about every 800 miles I had to add one quart. He recommended that I run Synthetic Mobil 10W-30 in warm weather and 5W-30 in cold weather.

Around 192K miles I began using one quart every 300-400 miles of interstate driving, less when driving city streets. I happened to mention this to my barber who is a rodder and biker. He recommended I go to 30 SAE. As the oil burning became more steady it was suggested I used 50 SAE motorcycle oil during warm months and 30 SAE during winter driving.

If I can pickup a 2nd car, I will park my 99 SC2, and attempt a ring job or have a pro fix it.

...
