How do you all get 6.2s to 300K miles

[nycxjeremyy]

I'd get it close and run it until it pukes. Might go another 200,000 miles .

I'd slap a bypass filter on & run synthetic oil it to slow future wear.

I can imagine the L E A K S from synthetic Rotella T6 as opposed to T4

I always preferred longevity over worrying about leaks. Around here, that's rust prevention

I run Amsoil in everything. Except when They had the clearance sale on the Mobile1

Rotella vs Amsoil vs JohnDeere vs anyone else. Go

Search best synthetic engine oils.

The Tribodyne that Chris sells is good stuff.

John Deere is usually good stuff - I don't know what they sell

Royal Purple is good, but I never liked the color.

I used Amsoil, with very good results. Where I am, I could order and sometimes have it in the afternoon.

Read the articles, watch the videos.

Did Project Farm do a best diesel motor oil test?

When the engine is warmed up and you start it- any smoke then?
Like- if you stopped somewhere for 1/2 hour lunch, when you start it to leave.

Also next time in the morning you start it, do this: cycle the glows 4-5 times.
Key on for glow plugs, dont start it but key off. Then immediately key on to cycle glow plugs again not starting, do this 4 or 5 times, then on the last one crank it to start. Then compare how much smoke there is.

Getting 300k miles from it now is like a 65 year old asking “how do I live to 100 years old?” Make improvements you can and enjoy when it is things like the fluiddampr you can go from this engine to the next one. You’re young enough that wearing out this engine and later putting in a new one that gets all the details built right will pay off because you can get 300k from it no worries.

Nope, its only when its cold

Granted, its been very warm here this past week (+85°F), if it does smoke, its very little and dissipates fairly quickly, I guarantee when winter comes (it gets down to -20°F) it'll start to smoke like a damn chimney.

Also. Reminder that when I bought this 1990 K5, this 6.2 was swapped in from an 85 K5, it had 78k miles when purchased so it is a relatively young motor, a young motor that has been taken care off (babied) as of yet.

(Yeah I should probably cycle the glows plugs more than just once and then cranking it straight away......)

The multiple cycles 4-5 will tell you 100% if it’s just a. Cold issue. I would suggest plugging in the block heater but can see your parking situation probably isn’t friendly to that.

Its like 45-60°F in the mornings here, can't possibly be THAT cold?

Id love to plug it in. Unfortunately, I got in trouble for doing so last winter when it was -15°F "ran a cable from my window"
