sludge build up. Why be synicle? I wouldnt use it. The better auto mfg use Castrol. Mobil 1 or Royal purple. As far as I know Mobile 1 is the only DEXOS certified oil. Its a super lube classification. The rest follow....
The yearly sale of VR-1 is a staple here. And if you've forgot'n, this site is about early stuff, like flat tappet's and not the current auto manufactured stuff that is all roller and have a cat system that won't allow zinc to be in the oil.
Funny stuff ..LOL I used it in my Harley for 20 years and ALL the cars I owned for the last 30 years with NO buildup of any kind. VR-1 is the only oil that goes in my 55 chevy and will til the day I don't own it anymore. Your "claim" of sludge just "ain't" true..
Almost all of those you already mentioned are DEXOS certified. Including Valvoline, especially their synthetics. I know because I use it. Just because you don't see a big flashy marketing scheme seal on the front, doesn't mean anything. Flip the jug over and read the small print. You will find its DEXOS certification listed along with all the other BS proprietary manufacturers specification certifications as well. I used Valvoline religiously in my OT silverado and it went over 200k mi with not so much as a hicup. Never had a spot of smoke, or any performance issues. It ran as good the day I sold it as the day I bought it new. The only thing that I ever had to replace was a water pump. I used valvoline in the silverado before that that went over 200k without any issues aside from a water pump as well. There's nothing wrong with it. And until somebody can show me otherwise with extremely well documented proof, I will continue to use it as it has never failed me before. This is going to be as stupid as the Chevy v. Ford debates. Let's take it for what it is, someone helping those interested in saving some dough.
I have actually done real testing for sludge build up on a multitude of oils including Valvoline, Castrol, Penzoil and Kendall. Valvoline came in second and Kendell came in first. Care to guess who came in last?? Yep, Castrol. In all fairness Mobil 1 and Royal Purple were not tested. Good luck with your Castrol....
Valvoline user since the 1970's-and NO oil-related issues. Max-Life in the 2002 GMC(4.3 V-6 with factory roller lifters and almost 170,000 miles);All-Fleet 15-40 in the 1990 Chevy truck with a 305(F.T. hydraulic with 168,000 miles) and VR-1 40 in the '64 Plymouth(413,f.t hydraulic). Enough older hands than mine recommend the zinc content for ANY flat tappet engine. Just my .02 cents ,adjusted for inflation,of course.
I talked to my machinest and he had never HEARD of ZDDP! he must be liveing under a rock! My wifes bonneville SSEI took out the push rods and rockers because of the low ZDDP thing! my mechanic said changes a lot of rockers on new style engines
I bought an old Chevy suburban with about 110K on it, 454" that the owner said was junk. Pennzoil from new. I didn't care, I was going to use it for parts, but just for the hell of it I changed oil in it and started driving it. I put Valvoline in it, as I did all my vehicles. It smoked like crazy for a while and then stopped, I changed oil every 2-3000 mi. It got better and better. I drove that thing hard, so did my teenage son...for well over 100K. It got rear ended so I sold the engine to a guy to rebuild, He took it apart and he didn't even get his hands dirty doing it. Absolutely spotless inside.
Valvoline VR-1 1400 PPM of Zinc, 1300 PPM of Phosphorous. Been using it in my flat tappet engines with no problems.
There are 2 kinds of VR1 the one that says "Not street legal" is the good stuff. The regular VR1 racing oil has slightly less. 1300 and 1200
All I am sayin is, I wouldnt use valvoline oil. Its not dexos certified yet, and has a known sludge problem. GM used it in their LT1 and LS engines, and is why the dexos certification came about. GM stopped using it, and rolled their sleeves up and cured the problem. Its not for me. Some of us expect more. But its fine for others. Perhaps that is why there are so many brands of oil on the shelves ? plus it keeps the thread at the top during the sale for those who use it.
FWIW, Valvoline says they refuse to pay the GM license fees. http://www.valvoline.com/promos/dexos.jsp I wonder if the GM sludge issue might be related to a poorly designed PCV system. Not that it matters much for typical HAMB-friendly usage.
Shitty materials perhaps. Those millions of Jeep Cherokees you see on the road all have flat tappet inline 6's.They last well over 200K miles without any special oil.
Well, I have used conventional Valvoline in several lawn mowers, cars, trucks, and street VR-1 in BBF jet boats and HP engines, for over 40 years, and have NEVER seen any sludge or residue, and that includes a 36 year old B&S in a lawn tractor. Your statement about sludge is simply not true.
I still find it kinda funny when I get excited about oil that is "ON SALE" for "ONLY" $3.99 a quart! lol
You have said this before a while back without showing any facts. I have been using Valvoline racing oils for 20 years, drag boats, race cars, muscle cars and have never ever had a sludge issue.
"Other's" as in our selves that stay on top of keeping are oil changes promptly on schedule. GM didn't change oil because of it's make up/formulation, it's the lack of there customers not doing the job of maintaining their vehicles. The stupidity of those GM owners cost GM in false warranty repair work. What other choose did GM have, or any other car builder for that matter.
i too believe that changing oil regularly is the most important part of making an engine last a long time. while i change oil in my hot rods and motorcycle with Valvoline oil and Wix filters, the daily drivers goes to the quick lube place. my `95 S-10 with a 4.3 had 287,000 miles on it when i sold it. all oil changes except one was done at the quick lube place....so you know it got the cheap oil and cheap filter. i was very good at having it changed at 3,000-4,000 miles i wouldn't have hesitated a second to drive it across the country. as far as i know it is still going strong
