Starting to get cold up here.

I’m gonna do an oil change. I know doing it when car is warmed up is best. What temp should I warm the car to?

51 MERC-CT · 10-23-2018, 04:11 PM

Operating temperature.

Then fill it back up with Walmart's new synthetic 0W-20 supertech like I do on my 21-studder for the winter. $16/5qts. Jack E/NJ

Jack

I always use rotollea 15/40. My engines are well worn/used - 40k miles

But eagar to learn. Why do you use syn?

30-9 Drive the car a few miles to bring the oil up to operating temperature. Then drain and refill with the correct oil. You don't say if your engine is a new rebuild. Mine 8BA is not. I use 20W50. I would not recommend synthetic or the thin oil mentioned above on an old engine. It is my understanding that modern oils like 0W-20 are used on modern day engines built with very tight tolerances between moving parts.

19fordy thanks that’s more inline with my old school thinkin.

Hotter the better it drains. I'm nearby in northern NYS and use standard high detergent Penn 10W-30 year-round. Have no filter and change oil at 1000 miles.

I am with 19fordy , I run 20-50 in everything and have no reason to change.
Why would you run 0-20 it must be like kerosine and give low oil pressure readings and inadequate lubrication on the old jalopies.

19Fordy · 10-24-2018, 01:54 PM

my4dv8: You are correct. My 2018 car uses 0W-16 oil with recommended oil changes every 5000 miles. The oil is like water. Future new oils will be even thinner.

>>>my old school thinkin.>>>0-20 it must be like kerosine and give low oil pressure readings and inadequate lubrication>>>

Not quite like kerosene. That's more like old school single weight oil technology thinking. 8^) Modern oils have additives that maintain more uniform flow viscosities throughout the temperature range of a running engine before its fully warmed up and add shear thickening strength at bearing interfaces where its needed most. Kerosene, diesel fuel & single weight oils don't behave like this. So in an old but refreshed 21-studder at fast idle, 0W-20 synthetic gives a fairly constant 20psi from cold start to warmed up. 5W-20 about 25psi cold gradually decreasing to 20psi warmed up. https://www.selectsynthetics.com/par...iscosity_Grade Jack E/NJ
