Can you use regular PCMO in small motors that don’t have oil filters?

I like how thick this 30 weight oil is but didn’t know if the higher zinc and phosphorus content is counter productive for a modern push rod engine. I tow an 8,000 camper in the Rocky Mountains and wanted a motor oil with extra protection. Ford “recommends” 5-30 for most situations and 0w-30...

I own a 2023 Kubota bx1880 that I bought last year in Iowa that I used on our farm that’s at ~800 elevation. I moved back to Colorado and I recently brought my bx1880 back to Colorado in the mountains at 7,400’ elevation. I noticed it takes a few more seconds to start as if it’s in the...

I have a bx1880 that I’ve always put 15w40 in. I’m assuming it had 10w-30 as the factory fill. After the 50 hour service interval I put Kubota 15w40 in it. The owners manual only recommends 10w30 or 15w40 in it. Being a BitOGeR, I chose the thicker oiL for better wear protection. It has a...

With the issues that have popped up with the valve train on the Ford 7.3 gas would running a non api certified oil that carries like 1,200 ppm phosphorus and 1,300+ ppm zinc be a good idea? Is it too much ZDDP? Thinking about running Royal purple hps 5w-30 since it has A LOT of ZDDP in it. I’m...

I traded my 2022 ram 3500 6.7 Cummins for a 2024 F250 superduty with the 7.3 gas. It was slightly used at 3,350 miles. Did an oil change in it with Castrol Edge full synthetic 5w-30. It meets the Ford specifications but after I did the oil change I looked up some VOA’s on the Castrol full...

I have a 2024 crosstrek that I’ve put 16k+ miles on in almost 6 months. I change the oil every 3k miles. It currently has 0w-20 in it. I have put a little over 1k miles on this recent oil change and I’ve noticed the oil level in the dipstick is lower, by about a quarter inch from the full...

I know its been talked about a lot but my new 2024 crosstrek calls for 0w-16 or a in a pinch 0w-20. I changed the factory oil out at 1,300 miles and put in 0w-20. I Know the recommendation for thinner oils in owners manuals is usually CAFE related and I want to to put 0w-30 in but ive been...

Has Subaru finally made a reliable turbocharged engine? I know a lot of modern GDi turbo engines have problems but I remember turbocharged roo’s from 20 years ago had turbo issues revolving around the wastegate.

I grabbed 15 quarts of it for 25$/5 quarts at waLmart because its cheap. I'm currently running it in my 6.7 Cummins because its cheap and I like the additive package. It's not Cummins Engineering standards 20081, but i read somewhere specifically that Cummins Engineering Standards 20086...

I was changing both the primary fuel filter and chassis filter on my 6.7 Cummins When I was installing the new mopar primary fuel filter the paper media bumped along side the engine and left a black smudge. Normally it wouldn’t concern me if the fuel was filtering from the outside of the filter...

My 6.7 Cummins is going into regen mode every day.. I’ve put 46k miles on it in 20 months. It has A LOT of highway mileage, never thought I’d worry about a DPF issue this soon. Made an appointment at my RAM dealer. Tech said it had something to do with the emissions equipment. Anyway, I can’t...

My 2006 Jeeps wrangler with the 4.0 I6 gas engine has black motor oil after 1,800 miles. It’s black black like diesel oil. Its oriellys 10w-30 synthetic high mileage. The oil level isn’t rising on the dipstick but it’s black now. Last time I checked it was after a few miles when I changed the...

I'm in the market for a new or newer fuel efficient vehicle. not interested in a hybrid, electric, or PHEV vehicle. I'd prefer something that isnt GDI or something that wont dilute the motor oil.. I havent been involved int the new car market for some time. Im kindof interested in a new or...

I've heard two older guys (one a mechanic and another a OTR trucker) in real life tell me to avoid rotella. I'm a fan of it because its consistently around $22/gallon at walmart. Anyway both of them said it should be avoided, one said its gritty when you rub it on your fingers after an oil...

Article is three years old but this stuck out to me: Straight out of the gate we recommend 6000 km (3700 mile) oil changes if you are running conventional oil 15W/40. This should be a safe interval for city driving, stop and go driving, and idling. Some vehicles can get away with a 8000 km...

What is the best anti west additive in diesel motor oil? Phosphorus? Zinc? Moly? Boron? I’ve seen on the HDEO’s that one oil might have a LOT of moly and boron but kinda meh levels of phosphorus or zinc. And then some HDEO’s have a lot of phosphorus and zinc but meh moly and boron. Or no moly...

I have a Kubota bx1880 sub compact utility tractor with a 0.722 liter 3 banger diesel. It only has 16 hp so no EGR is equipped on it. The Kubotas owners manual recommends 10w30 or 15w-40 for multi grade oil. what's interesting is that they have two sections for oil rating. One is for non EGR...

I’ve been buying a lot of fossil fuel burners lately, I ordered a husqvarna w520 with a Kawasaki FJB180v kai It came with a little smoosh of oil in it, as it was shipped in a box. I went and grabbed some Casey’s brand 10w-30 for the initial break in of 8 hours. The problem I see is that the...

I've heard this a lot, Turbo charged engines "need" synthetic oil to prevent coking of the oil on the bearings in the turbo after you turn the engine off. I always idle 3-4 minutes when I park after highway driving and maybe 2.5 minutes after stop and go driving. The idea is to let oil circulate...
