What engine oil y'all running now?

[ekrampitzjr]

Bought a bike back in 88, changed the oil as soon as I got it home. When I pulled the plug, oil came out like hot water. That's what happens when you put car oil in a motorcycle. Destroys the oil in short order.

Red Line, which makes only full-synthetic oil, has a special 20W-60 heavy-duty powersport oil just for V-twin motorcycle engines. Really.

Went to an oil change place that just popped up, and got 5W20 full synthetic for my '08 2.3. I don't know what brand. The truck ran quieter than it ever had before, with more power. Yesterday I got under the truck to check some things, and it's leaking from the oil plug. Doing my own change next time, but apparently it likes fancy oil and 100% dino fuel.

I think it is an additive that reduces noise. I ran Chevron synthetic blend and Motorcraft oil 10+ years ago. I could hear the the valvetrain with the Motorcraft oil. I started running other brands for awhile when Walmart took Motorcraft and Chevron off the shelves for awhile. It is quiet with Castrol Edge, It has some noise with Kirkland. Less noise with 5w-30 than 5w-20.

Castrol Edge is supposedly good for 25,000 miles, from what I've seen. Was getting ads on my phone about it.

Maybe for leaking Harley's? Long time ago, worked at a Chief Auto Parts. We sold a sh-t ton of Valvoline straight 60 weight to Harley riders. Second to that was Castrol 20W-50. When we had oil sales, that stuff flew out the door. More than the 10W-40 did. We bought 20W-50 at twice the rate of 10W-40. The Good Old Days!!

BTW, all the buildings that were once Chief Auto Parts, became Auto Zones in a weekend.

It may be "good for 25,000 miles" but oil needs to be changed because it gets diluted with combustion byproducts and moisture, not because it failed somehow. The only oil I've ever seen fail was Castrol,after a few thousand miles the consumption went way up. He'd change his oil and the problem disappeared.

Right, if you start it, drive it right away, and only for short distances, that is a problem. Even though I only live seven miles from work, I warm if five minutes or so, drive it the long way going and coming, and don't shut off immediately when I get where I'm going. It's said that if you get the oil to operating temperature, and keep it there for 15 minutes or longer, it's not a problem. The heat allows the oil detergent to eliminate those by-products.

But other than my sister putting over 40,000 miles on the truck without changing the oil, myself, I don't go over 10,000 on the truck. That 40,000+ fiasco did not harm whatsoever. So I am not uncomfortable with 10,000.

Also, I just don't see how the oil doesn't shear out of grade over that many miles and heat cycles and the additive package not degrade to far below efficiency. Which the shear may not be the worst thing in the world if you're running say a 5W-30 and maybe it shears closer to a 20, which many are running a 20 weight oil anyway so maybe not a terrible thing. But I just don't see how, in most situations, 10,000+ miles just isn't too much with everything taken into consideration, much less 25,000. Heck I'd say there's plenty of people that drive their vehicle super hard in harsh conditions that may not even be able to get a solid 5,000 miles between OCI's.

Did you see where I posted that my sister borrowed my Ranger from 2009 to 2013, put over 40,000 miles on it and never changed the oil. And it did no harm to the truck whatsoever. 13 years and 80,000 miles later ,still no leaks or burning of oil. After that, I have no problem with 10,000 miles changes. I only use good full synthetic oil.

My 2021 Honda CBR600RR, Honda says if I use their GN4 10W-40, it's good for 8500 miles. IN a small bore engine that revs to 15,000 rpms. And the engine oil does the transmission. I changed it last time at 10,000, fully warmed up. Came out nice and thick like syrup.

I guess if Castrol is using some advanced additive package, they don't feel that 25,000 miles is a stretch. Like Honda with their oil.

if you run extended drain intervals you need bypass filtration and sample monitoring.

running past 5 k without sample monitoring is stupid.

the new engines with valve variation...especially eco boost platform and coyote only benefit from 3-4 k change with high end oil.


the valvoline protect and restore line is the only thing i will put in my pushrod engines now.


and any modern engines off of warranty.

people hit the lotto. people get hit by lightening.

and for older engines...the simple truth is with efi that is running ok....you can probably just add oil as it burns it for the first 150 k with tier 1 oil.....no matter brand....

but that engine wont be a reman candidate.

Yep I saw that post. Very interesting for sure. I have a younger sister and if she had done that to my truck...well it sounds like you took it a lot better than I would have. I mean it's quite possible it didn't harm the engine. It sure didn't do it any favors though, I'd think we can agree on that. But, maybe it took 20,000 miles off whatever life is left in the engine too and didn't do any "immediately noticable" damage. I'm really not sure how one can say one way or the other without actually tearing the engine down and looking at it. It's hard to prove a negative in that situation I guess. I'd say you probably wouldn't recommend to anyone to do that to an engine though. I'd tend to also think if you were looking at purchasing a vehicle and someone told you the engine hadn't had the oil changed in 40,000 miles, it would probably be a no go on buying it, or at least a huge price drop in the offer. With all that said, if a vehicle is going to get away with that, an older Ford ranger is probably one of the few vehicles that could do it.

You're quite correct on all points. Time will tell on the mileage thing though. 206,500 currently. No sign that it is going to blow up anytime soon. No unusual sounds or anything like that.
