Oil Change Frequency

It sits in the pan all winter and collects moisture, but I guess thats what you can do.

I'd just drain it and zip tie the dipstick to the battery cable after disconnecting it so I dont forget.

I change mine by color which seams to be about every 2000 miles on my current 410 only because I live at the beach, its solid roller and driven on the street.


When I race I run a K&P removable screen type billet oil filter Store and change the oil A. By color or B. As soon as found any metal/parts debris in the oil filter screen ...lol
I'm funny, it kind of depends on what's in the motor and what I'm doing with it. If you pull the dipstick wipe it on your finger and it doesn't have any golden aura 'around darker center' left on it 'or green or red depending on the oil you use'...then carbon is taking over and diminishing the viscosity and overall film strength to hang on the bearings, lobes etc.

Now I'm running a street roller of course I've up the pressure beyond what they told me I needed because I just couldn't sleep at night with that little seat PSI... So I change a little early maybe just to keep it extra clean.

My 340.... every 7k with 2 filters along the way, but only with Schaeffers oil.
