Keep with Conventional for 2001 Buick? #5264609 11/11/19 09:44 PM

My aunt owns a 2001 Buick LeSabre with 53k miles. She keeps it garaged-kept and barely drives it. (She elderly and basically takes it to the local store or appointment.) The car is in awesome shape and I have done all the maintenance on it since new. I go by the OLM and it's around 11% now. It's always had a steady diet of 10W-30 Chevron or Pennzoil and WIX filters. Conventional "Dino" oil as you refer to it. It maybe gets one Oil change per year.

My question...

Since Walmart Supertech Synthetic is so inexpensive now, would be of any benefit to change? It might sound like a silly question... but I'm just throwing it out there...

What oil is considered the "best" conventional these days? I really don't mind spending the extra money to keep it going... but with very few miles driven each year, does it behoove me to consider a full synthetic?

Thank ahead of time for your thoughts!

I don't buy conventional any more. I just don't see any reason to.
The best conventional oil is any oil that meets your engine's spec.
And just think how well you will sleep with the syn?
Good luck!

Big spread when you have it changed, and --living in a condo-- I'm not allowed to change it. Plus I've stocked up with $10 oil change coupons. When my VWB runs down a few ounces I throw in some Harvest King syn 5w30-- that or ST would be my pick if I was changing my own. Warren or Warren, sleep well and save $$$.

SN "conventional" is a syn blend now due to more stringent modern standards. The Walmart synthetic is a great deal, and there is nothing wrong with using it. I would use house brand synthetic over name-brand "dino"

Even the cheapest oil that meets SN standards is better than any oil available in 2001 when your car was new smile

Napa has their house brand synthetic oil on sale this month for $3.49/qt. It is Valvoline

18 years and only 53,000 miles. Have you ever seen inside this engine?

My first inclination would be to stay the course with what has been used up to now. Most conventional oils are blends these days. Pick a brand and run with it. Keep an eye out for sales and promos.

Minor point, but many SN oils that are 5w30 blends are 10w30 group II. VWB has declared their Daily Protection 5w20 and 5w30 to be blends and their 10w30 to be conventional. This ticks off a small portion of reviewers on Amazon and what not who associate synthetic and cubic zirconia and want "real oil" and not "phony oil" just like they got their fiance a real diamond and not a fugasy.

I have not seen the inside... I did a full coolant change along with brake & power steering flush last year. (I've heard the 3.8L is a rock solid engine) Also heard there was some Dex Cool issue with gaskets? Nevertheless... it runs like a top. She says one day I'll inherit it... LOL... It's a great car and on the highway, I've routinely got 30mpg going 65-70mph.

Appreciate the replies everyone! I don't want to "cheap out" on the oil... and I'm not a Mobil 1 fan. (I have a UOA coming on my 2008 KIA w/Supertech soon) Hopefully this will give me data. I use my KIA much harder that the Buick.

Think the ST high mileage syn is the same price as the non-hi mileage syn. That's the new "low end" syn fill and filter at Walmart--bit over thirty bucks. Despite the low mileage, that would be my choice if I was changing the oil myself.

What engine?

As I've proven, the 60 degree GM V6's are incredibly easy on oil. 60k mile oil changes are a distinct possibility.

The 3800 V6, which is probably the engine in that car, is also reputed to be very easy on oil. Throw in a decent quality 0W-30, make sure the level is kept topped off, change the filter every 15k, and similarly, you may never have to change the oil again.

Yes, you are correct, it is a 3800 v6 engine. The car resides in Arizona, so I'm not sure how a 0W oil would be of any benefit. I can't imagine never changing the oil. I can do yearly or mileage based changes but I can't see never changing it...

With that low of miles annually (3k'ish), the benefits of switching to a full synthetic are marginal at best. Don't fix what ain't broken.😉

How often do you change the oil/filter?

YES, stick with what you're doing. PYB is a great oil. Maybe even move to 5W30; I use PYB HM 5W30(or most HM oils) in the '80 FORMULA in my signature.

Because your aunt only drives the BUICK once in awhile, the 5W may help with (just slightly) better startup lubrication on those rare occassions that she takes the car.

AND YES AGAIN. You can move to synthetic oil as it is cheap at Walmart*. But, should you?

However, if you're changing the oil & filter once per year then stick with conventional. Maybe even move to SuperTech oil and you'll spend the same money for the oil & filter as the PYB alone!...I realize you mentioned the money isn't an issue. smile
