Changing oil brand after 200,000 miles?
I have changed my own oil every 5,000 miles using MB branded 229.52 oil that’s been easy to find on Amazon. But it’s getting slightly harder to find (I don’t want to pay dealer prices) and even on Amazon it’s slightly more expensive than other brands.
I’m thinking of switching to liquimoly for the next oil change. They make a 229.52 spec oil. No overriding reason other than it’s a little cheaper and easier to get.
I’m also thinking that changing to a different oil brand after 200,000 miles might be a bad idea. I’ve owned her since new and never had any engine issues, and she still gets 40mpg on the hwy.
Thoughts?
No worries.
I asked my dad the other day still driving in his 80's went thru many cars...
Ever had an engine fail? NOPE...
People worry about engines failing when it is a rare thing from just the oil you used....
Now engines fail for design reasons and NOT changing the oil but that is not the same thing.
Go for it save some $$$$$





Can't see how one can do better than Wally World's 5-qt jugs of Mobil 1 0w40 for just $23 or so.
Drive to any Walmart, cheap price, done.

Maybe they don't intend them to travel those distances anymore. Cars are increasingly disposable.
"You can go into any mass retailer (Wal-Mart, Meijer, AutoZone, etc.) and buy a 5W/30 (or any other grade) that will perform well in your engine. One of the best-kept secrets of the oil industry is that these store brands are actually the same, quality oils that are produced by the major oil companies. The only difference between these products and the major company brands is the name on the container and the price. Don’t believe us? Try running your own experiment: do a sample on Oil A after a known number of miles, then do a sample on Oil B and compare the wear levels. You may see a little fluctuation, but it’s very rare for one oil to make a significant difference in an engine’s wear patterns."

No need to change if you don't have to, but if it's not
OE MB, Mobil-1, or Liqui Moly
then don't use it!

OP certainly qualifies for the 250,000km badge (155,000 miles).

It's better to say a spec is a spec , as in a manufacturer oil specification should be made up of a preset list of ingredients ( recipe ) to achieve that manufacturers oil performance profile .

With 5000 oil change I'd send the sample for lab testing. Per all the knowledge, you are harming your engine. Not much, by slimmer chances to get it to 1 million. miles
I liked Castrol living in Poland, but the good weights are not making it to USA.
