I inherited a 2006 Chevy Impala 3.5L V-6. Has 41,800 miles. First car in along time. First Chevy in a long time.

Was my grandmothers car, she had a indy shop do maintenance, which I have no records of other than the OCI sticker on the windshield. Looks like every 3K was changed.

I don't know if this engine is hard or easy on oil. Its a pushrod VVT engine.

My wife is going to drive it for work. Mostly will be highway miles, min of 20 miles one way, half will probably be 150+ miles one way. I plan on 10K OCI using probably M1 or PPPP, easiest to find here. Probably use a Fram Ultra.


Anybody see any issues with this plan? Or better recommendations? I don't know anything about the Dexos certs, so not sure if I need to make sure I use a Dexos oil?

Thanks

It doesn't need the dexos 1 oil but it wouldn't hurt to run it.

I change the oil on a friends 2011 Impala with the same motor and it has 145k on it. I started changing it at 45k and around 120k it started to use oil. They would go by the OLM and it would usually be around 7 to 8k on oil changes. I noticed that the last few oil changes when it came in it was low on oil by half a qt. They started using AC delco oil filters with AMOIL's OE 5w-30 at 45k and that is it's steady diet.

Good plan. Those good oils are of course already dexos1 approved, a higher level of performance than plain old SN GF-5 oils.
Fram Ultra is good plan, agreed.
The car's OLM is very good at predicting oil degradation, so go by that exactly, a sophisticated algorithm takes into account necessary variables to alert you when to change.
Another dexos1 full-synthetic is https://www.walmart.com/ip/Milesyn-SXR-5...-of-12/49107856 which comes out to about $1.85 per quart with tax.

Great engines which seem to be pretty easy on oil, but with a pretty small (4 qt) sump. I have 130,000 on mine (in a Saturn Aura) and engine is still running great especially with new spark plugs. The 4T45e transmission, on the other hand.... Has a reputation of lasting forever even with jarring, slamming shifts, but definitely isn't fun to deal with in city driving.

Yep. This engine was the first ever, I believe.

As said previously, not terribly hard on oil AFAIK but not a huge sump for the size of the engine. 7,500-10K highway miles on full syn shouldn't be a problem. Only non-standard repairs I've done to a 3.5 are an oil pan gasket/fromt motor mount (250K-mile Uplander) and the oil filter adapter gasket on an '05 Malibu. I believe the 3.5 was better but not completely out of the woods of the 3.1/3.4's propensity to blow any number of cooling system components and usually head gaskets immediately after, so keep that system checked up on.

Looks like the Impalas along with the other heavy gm cars got the 4T65e trans. Though it looks like it suffers the same kind of quirks as the 4T45e.

I didn't know its only 4 qts. Maybe I will go by the OLM for the first OCI and see how it goes.

I believe the OLM in that Malibu tripped in the 6-7K range, so that could be a good place to start. And I haven't known the 4T65 to be a problematic trans.

I would definitely go by the oil life monitor. You could use practically any oil in that engine and it would be happy. I would use Mobil 1 or even Supertech Syn and be fine with it.

Unless the OLM has not been reprogrammed by the dealer. The one on my 2006 Cadillac had to be reprogrammed to a lower interval because so many other folks with the 3.6 engine had experienced various problems that GM realized the OLM was set too long. I never use it anyway.

That re-programming for OLM was exclusive to the 3.6L only and was an attempt to reduce timing chain failures.

The 3.5 in that era Impala is not a VVT engine. The 3.6 in the 2011 and up is a VVT engine.

I have the 3.5 in our 2010 Impala. I run either a syn blend or a full syn with the ACDelco filters per the OLM and it's been fine. Just passed 120K miles on ours this past week. It does use about a quart between changes so I keep a close eye on it. Like others have said, it's only a 4 quart sump.
