worn spark plug gaps are stupid wide when they need to be replaced There is no maintanance interval where the spark plugs are removed and regapped every 20Kmiles or so. They just let them go until you start getting poor gas mileage or they get fouled due to another issue (Valve/piston ring...
it takes energy to shear anything. The higher the RPM the higher the energy imparted into the oil on each stroke. This will create more heat and make it break down faster.
Yup,
In the hot temperatures the 30 would be the more important number anyway. Rotella generally gets good showing on testing and additive pack. Should be fine.
I saw a generator silencing video that a person tried to put a car muffler on a generator to quiet it down. Barely moved the needle. The noise came from the engine and the carburetor.
That's why I call NGKs bought at Amazon NG maybes.
I think i have seen videos where you can contact NGK with the serial number and see if they are sold through Amazon.
You have to read the carfax on these cars. Sometimes they sit there for a reason. Crash history, sketchy oil change interval, 4+ owners in a short period of time. I was looking for a new car as well. I went with Enterprise rental car sales. Still need check the carfax for them so you...
looks like fungus. Easy just treat one patch with greelight and see how that works. Spray another patch with insecticide that kills grubs, chinch bugs and webworms. (Bifenthrin)
2005 likely called for 5W30. "Hybrid oil" would have been synthetic blend which is code word for very good conventional. As long as 5K oil changes were done it should be fine.
Tomioka, How did you manage that deal? I hated waiting in line. Counting the drive there and back it was close to two hours to have them do something I could have done in 15 minutes. AND got to see the oil coming out looking for rainbows.
So.....
I bought a 2023 Tacoma last summer and am on my first oil change at 5K miles. I thought long and hard about changing it earlier but decided to wait until 5K. As some of you know, toyota has a 2 year 25K mile, maintenance covered plan. AKA Free oil changes and rotations...
CHECK THE SEARCH BUTTON!!!!! << Mean FACE >> :)
I don't think there is a "real life" measurable difference between then. I've been on this forum a LONG time and the one thing that is certain is that the oils are all converging. As long as they have an API specification they are all...
