This concerns a very late model engine that are finding their way into many swaps. No it’s not an LS. My newest vehicle started using oil after 10k miles. Under warranty it went thru 2 oil consumption tests. Its factory oil was 5-w20 semisynthetic. It did not consume what was “excessive” so it stayed the same. I did as much investigating as a laymen could and from an anonymous factory tech found the engine was manufactured to use 5-w30 but under EPA and other government agencies 5-w20 was used to meet fuel milage concerns. I changed at about 20k miles to the 5-w30 and now have 42k on the engine and the oil consumption is negligible. Oil weights do matter as the 6.2 L engines from GM are currently finding out. I like the discussions here as I learn from others experiences.
It may be common knowledge but for those of us that own and drive diesel trucks we see first hand the filthy black oil at oil change. Diesel engines produce a lot of soot that ac***ulates in the oil. Hence the diesel oil formula which has way more detergents and dispersants than standard motor oil. This allows the soot to be cleaned and then removed at each oil change. There is no real advantage to using diesel motor oil in a gasoline engine. You will be better served by using a good oil designed for your engine.
Even 25 years ago they were putting in thinner oil at the factory and on the cap than engineered for. On my off topic rod every oil cap from that engine said 5w30. Out of habit I just ran 10w30. Finally got an oil pressure gauge in the car(just had a low oil pressure light before) and tripped out when I was seeing 52 psi hot at idle. I thought it was way too high. Then a guy on a forum for that engine dug up the original engineering oil pressure "dyno" chart(my specific engine was from 2004). Turns out 52 psi hot was dead nuts perfect. And on the chart it boldly specified 10w30
I had one car, a Merc Topaz that used a bit of oil, I was always loyal to Valvoline for my Chevies. So I broke out the vehicle manual, and the oil recommended had some spec I was not familiar with. Switched to Motorcraft oil with the spec, it quit using oil..... I started reading maintenance specifications after that.
"Think I'll sit on the computer all day and argue about which oil is best instead of actually turning a wrench or driving my car"
Are we still talking about oil? I was busy getting a contract with a s****per set up, to haul away my parts when I die.
I know, and I'm sorry... kinda. But it occurs to me that, the majority of people over think way too much in life. Remember that cartoon that was on here of the guy at the car show telling everybody what was wrong with their car, then he rode away on a bicycle? Opinions.... I have a great friend named **** Parisey, retired Harley Davidson engineer, he was over the screaming eagle program, if you go on YouTube and watch Byron Hines induction into the NHRA hall of fame, at the beginning of his speech, he thanks God and **** for his success. In the 60's, **** was known as Dr. Speed, he wrench'd and crew chief'd nitro cars, one year at Bowling Green, we got into the whole cam & lifter debacle of today, zinc additives was part of the discussion, as Bob Martin, that was sitting there, retired lubrication engineer for HD. It was kinda entertaining to listen to these 80 something year old hot rodders argue over the same old ****. Finally **** asked Bob, why are flat tappet failures such an issue now? He said back in my youth, we threw every cam in a block, with 30w oil poured over it, no break in lube, no additives, and never had an issue, hell we didn't have a break in period any longer than setting the timing! Bob told him it was just dumb luck, to which **** replied "no they just sell junk these days, and try everything they can to band aid it".... I have rotella T4 in my wagon right now, and before I drive it to Bowling Green next month I'll change it to O'Reilly's brand with a bottle of rislone. Metallurgy today is ****, people m*** produce everything, and quality is way down the list, below profit and production. Spend your money wisely, buy Johnson lifters and let it go. When you install your lifters, ***ure that they drop in as they should, complete your valve train ***embly before you put the intake on, rotate your engine, are the lifters spinning? Do you have exotic valve spring pressures on an engine that will never see over 3000 rpm? Why did you do that? It's not rocket surgery, you're not in the lane next to John Force lol... now you bunch of closet street rodders get up from the computer, and go get your hands dirty
So your saying the lake soeed video is incorrect in ***uming the low detergent oil had fewer wear metals cause it’s creating less wear metals? and the claim that excessive detergents being bad is false due to the positive Lucas oil (contains more detergents than rotella) reviees are incorrect?
Engine break in was motor oil, sometimes some STP poured on the cam, then hammer down the road. All I learned from this thread is you should use oil. Oil is good. New parts are very suspect And oil science is voodoo
Yes. Scientist A says rotella (heavy detergents) are bad for gasoline engines Scientists B&C increased detergents and other additives beyond Rotella and label it as as vintage gasoline engine oil so its voodoo, ***umption or someone’s incorrect I use oil. I’ve had nothing but positive experience with oil
Now that Lloyd has commented on this thread, I’ll keep reading it. Just for the record, I agree with everything he said!!! I wonder what kind of oil I should put in the oil cups on my generator?……..
Good Lord, this thread is still going? WTF??? Some of you, you talk too much. You talk like you know what you're talking about when you haven't got an effin clue. Some one once said "a little knowledge is a dangerous thing", that's the theme of this thread. Please, let it go.
I think the funny part is the OP after posting engine info is MIA. He left a stinker in an elevator, walked out, and left everyone pointing 6 pages (so far) of opinionated fingers.
I never liked the Firesign Theatre too much but people thought they were funny. Glad some people remember them. Wonder what oil they used? We're all Bozos on this bus was referring a computer bus but it caught on whenever odd things happened some joker would pipe up with we're all Bozos on this bus. I find it amusing to repeat it today and see if anyone recognizes it. Now where did I put my gallon can of Booster Motor Oil?
Oh yeah !!!.........I don't have a problem mixing up 10W-30 with 10W-40 with 5W-20...whatever.... Oilz-oil.......**** that's in my ever day parts chaser Shivel-lay S-10. 4.3 with 1/4 million miles on it !! When "it" tells me it doesn't like its weights mixed any more....then I'll start stick'in to one weight.. 6sally6
I've lost many SBC cams over the years using Mobil Delvac, Mobil 1, Castrol, Royal Purple, Pennzoil, Quaker State and other "good" oils. Motors were nothing special, just daily drivers with stock or mild cams and springs... Haven't lost one in several years. Sent a sample off to Black Stone labs and this is what I use now...
