Examples of "low quality" oil?
- Thread starter CZ75
- Start date
My 2000 Honda Insight 500 miles shy of the maintenance light makes the so called “Gas Truck” 0w20 full synthetic into a horrible brown slurry which has never happened before m. It’s not driven a lot and I missed a time based oil change causing it to go 7000 miles and 2.5 years whereas usually I never exceed 3000-5000 miles a change.
This gas truck isn’t up to it.

Whatever
Interesting - I have never seen a 5W-30 conventional rated SP / GF6A. All the stuff on the retail shelves shows as "synthetic blend". All just marketing names I know, but there were people here looking for conventional 5w-30 not that long ago.
Also interesting is the retail 10W-30 is still listed and sold as "conventional"

Triax.
A simple 75w90 gear oil from Ultra 1 Plus lost over 30% of its viscosity in the KRL test…. I don’t care who anybody’s affiliated with; a result like that says “caveat emptor” for everything in their lineup, IMO.
City star oil
I was under the impression that the OP was discussing engine oil quality but that is good to know.
He was… but as a consumer, if something as simple as gear oil (where almost anything will provide 50k+ service) is soooo bad it’s literally out of grade within 24 hours of service, would you just blindly trust every product they make?
Good question. Most, if not all of their motor oils, are registered with the API which means that they should be suitable for automotive applications. We don't know what exactly caused their gear oil issue so I don't think it would be wise to throw the baby out with the bath water here.He was… but as a consumer, if something as simple as gear oil (where almost anything will provide 50k+ service) is soooo bad it’s literally out of grade within 24 hours of service, would you just blindly trust every product they make?
Line wash...lol have not heard that term, learn something every day.
Yep I found a quart of old dollar store SA rated straight 40wt earlier this year. I'll use it for chainsaw bar and chain oil, that's about it. Wouldn't even put it in a lawnmower.
If I remember correctly SA doesn't have to have any anti wear or detergent additives.

Lower head either near the top of the vehicle hood, or to the side of either front tire and listen inside the wheel well for............
........ tick ...tick....tick.....tick......... repeatedly and constantly.
Even occurs sometimes using 2Xs-3Xs more money boutique oils.
The sounds coming from an 28k mileage engine almost drove me nuts one time. Inside my engine was an array of Group 4 and Group 5 base oils with highly rated additives attached. I hesitantly decided one day to remove the 1.7k-used boutique oil and replaced it with Group 3 Castrol Edge.
Instantly, the ticking noises were gone.
We should never buy more than one OCI of any (new to us) oil brand. Then we should decide if repeated use warrants another purchase. Let us (the vehicle owners) not decide what's best for our engines. Let the vehicle tell us what it likes best, prior to larger (bulk-type) purchases.

To bad formula shell isn’t an easy find anymore. That was some of the best sub $2 oil I ever used. I ran that in my 09 Altima for years and it always produced excellent results.
