Hey Scotty, I’ve been doing some research and apparently Amsoil signature series says it can go 25 000 miles interval. Is this trustable and how often would you change it in a turbocharged engine?
Thanks for all the responses , Gonna stick with full synthetic Penzoil every 5-6k miles.
25,000 miles between oil changes? Sure, … if you don’t like your car! AMSOIL Signature Series oil? Sure, … if you have money to waist!
Look, I have no idea of what your chariot is like, … but I suggest just use what manufacturer prescribes. Keep it in your engine for as long as manufacturer advise - read a fine print in your owner’s manual for precise details. But, … something like 5-6,000 miles, … or six months interval between oil and filter changes will make your engine last very, very long with no trouble at all. Decision is all yours, …
F.S.
AMS oil.....Royal Purple. {black}:laugh:
Great way to waste your money. Every 5k miles/1 year, regardless of what color it is, what they promise, etc. is the only way to get the best life out of an engine. I've torn down plenty of motors that used those so-called Premium oils. Not impressed at all with the real world findings.
I live here in the Netherlands for 52 years and as a car mechanic 33 years. What I saw in my career through the years is that the oil change here in Europe are in general 25.000km. in the former day's (90's) 15.000km or one year was the standard. When working in those day with a vw/audi dealer. The put on the mileage for a oil change up to 30.000km. long life oil.....sure...;). My experience is that with the longer drain intervals more issues occurred. Premature wear, and more sludge issues. It seems to be that you have been in America change the oil very very soon. I understand that changing the oil at a 3000 mileage will help to extend the engine life. From my point of view 15.000km or 1 year should give the best results (personal experience) we in Europe drive most of the time short distances. I guess in the US the bigger country the distances seems to be much longer according driving. Why is your "standard" 3 to 5000k miles. Has it been educated by the oil industry over there?
Big Oil just likes to tell us to buy the best they make and do so frequently, though some specialty companies make crazy claims about going huge distances between changes safely. In my experience the 5k miles/1 year interval is the best for maintenance purposes and to keep wear down. Of course manufacturers will tell you to just change it when the onboard system says to, but that's because they want it to break just outside of warranty so that they can sell you a new one.
@mod_man you can’t even trust what manufacturers say anymore these days. Just open a Ford owners manual.
That's true. Sadly.
I would go with true and tried, and that is every 5,000 miles.
That's about as believable as "lifetime" transmission fluid. Just change it every 5,000 and don't try to shortcut or save money. In the end, that will get you.
That’s one way to prematurely ruin your engine & turbo..
Cause turbos and engines are cheaper than oil lol. For real though, with a turbo if anything you should be changing oil more often rather than less. For the new metallurgy of say a newer car (2015ish+) 7k is ight for the latest I would say. Then again I would never do it at 7k for my mom's VW cause she has the turbo. Thing needs clean oil any chance it gets..
Even if your engine uses 1 Qt. of oil every 5000 miles, it's gonna be empty at 25000.
Maybe if oil was $400 a qt. but until then every 4 to 5k.
No way. That is to risky.
