[1990Legend_LS_5spd]

Ok guys ... this normal?
1990 Legend .... original engine .... 127k miles .... after 5k miles the engine oil still looks like it could go another 2-3k ... im running Castrol GTX High Mileage 5w30 with a Wix filter ... how does your oil compare at 2k? 3k? 5K?

i dont drive mine past 2.5k but at that point its darker than the fresh stuff but not black no sparkles (metal flakes)

 

[1990Legend_LS_5spd]

mine is never black ... you can still see through it as it pours ... like maple syrup

 

[88_acro]

exactly thats the way its supposed to be

This depends on many factors, the main factor that changes the oil to a black color is piston ring sealing, the worse the piston ring seals the more gasoline gets mixed with the oil, this dirty's the oil faster.

Also carbon buildup is another factor.

If your oil is still gold/light brown at 3k then your engine is healthy and has been well maintained.

Also keep in mind it isnt uncommon for newer cars to have black oil at 3k since new engine's take time to break-in before they start to operate properly.

Are there any additives or treatments that target this specific area?

I Think the higher mileage oils/additives focus on restoring rings
sometimes they help, mostly its preventitive maintenance I think.
Mobil1 supersyn higher mileage cut my oil burning in half but that might be because it was syn (doesn't burn as easy).

I need to change my oil very, very soon.

What would you guys recommend? Some particular high-mileage brand?

TIA

Castrol GTX High Mileage! In my opiniton ... best stuff you can buy!

 

[2.7legend]

thats how the oil looks on my legend well minus the metal shavings now.
before i would change the oil at 1500miles.

Actually 3k on dino oil isn't that bad, you could probably take it to 5k no problems, just because the oil looks dirty doesn't mean its not doing its job. Check this site out for all your oil concerns.
