Curious on what people think about running syn-blend in an 02 lesabre. Looking to run it because I want a 10W-40 but its nearly non existent in full synthetic. If anyone has any thoughts or experiences with supertech or quaker state all-mileage, or valvoline maxlife synthetic blend please share. Or any used oil analysis to share. I want to know if it would shorten the life of my engine at all compared to a full syn doing 3k OCI.

There's Mobil 1 High Mileage 10w40:

I am aware of this but I usually do 3-4k mile OCI’s regardless so I don’t think spending 10 extra dollars would be worth it in my case.
Mine is actually 10W-30 after 2002 they switched to 5w-30 I believe, these engines run very hot so a thicker oil will be better for these is what I have heard.
This! It was pretty common to get 200k miles out of a 3.8 GM V6 back in the 1990s using whatever conventional or blend API SJ/SL oil was on the shelf back then. Any API SP/SQ oil you buy today is likely many times better than whatever SJ oil people were using back then.
Any modern synthetic-blend oil would be more than sufficient for your vehicle if it otherwise meets spec. Heck, even brand new Mustang GT's with ~500hp come with synthetic blend from the factory. Respectfully, you may be overthinking this.

Don't see the need 40, I would stick with a good 5 or 10W-30 Conventional ILSAC.
Those should be all SS regardless of that the bottle advertising says.

I'm voting for Valvoline MaxLife because have used their 5W-30 synth. blend (red jug) for about 10 years with no issues.
3K OCI would be perfect for the engine with this oil.

I would think a blend would be more than fine with 3K to 5K OCI. I'm not a synthetic "fan boy" for every application and have had good experienced running Ford / Blend oil with 5K OCI in MANY Fords the last 10 years or so. If I was going more than 5K I would perhaps use a full synthetic but that just me. 3K I would think any oil would work as long as it is spec for the car using it.
I've used a ton of the Valvoline Syn-Blend High Mileage in the red bottle. Good stuff at a great price.
True of 98% of the posts here. Including mine.

I've always run Valvoline High Mileage synth blend oil in my very high mileage Miata. Good stuff, imo.
My Daily is a 2000 Buick Century with the 3.1. It had 24k on it when I inherited it 5 years ago and has 108k on it now. It gets 5w30 High Mileage SynBlend in different flavors. Valvoline Maxlife, Castrol GTX, Providence (rural king). OCI’s are 5k. Engine doesn’t use any amount to speak of.
Like was mentioned before any SP/SQ is far better than what it would’ve gotten when new. Pick one and enjoy.

The 420K mile Xterra in my signature has run its whole life on conventional or semis syn on short OCI.
I am in no way saying there are not good oils and better oils, but "synthetic" is a marketing term anyway.
I have run 10W-40 Havoline recently. I think most 10W-40's will be pure "conventional" for example?

Is that your analysis based on your 5 months here?
I run synthetic blends because they meet the recommendations for my car and are available at the ~$20 price point which is where I like to shop. Running Castrol GTX Ultraclean 5w20 currently.
