Valvoline 5w-20 SynPower Oil??? - SRT Forums

RiotMaker · 01-17-2013, 11:40 AM

I told the mechanic to use 5w30 and he put 5w20 valvoline synpower oil instead. Will this oil be all right in my car????. He said it is the same thing...... and will be alright in my car.

Take It back and tell him to do it right. It is not the same. That oil is too thin to be used in our cars

Just because 5w30 is the 'recommended' oil doesn't mean that's what you have to use ALL the time. Various factors can play into it, weather mostly. Depending on where you live in Albuquerque, it can get cold. And since it is winter time, thicker oil and cold weather don't mix well. It can cause hard starts which wears on your starter. In the winter time I ALWAYS go to a thinner oil.

In the winter time I ALWAYS go to a thinner oil.

The first number of the oil grade is the 'winter weight', meaning it flows like a 5 weight oil when cold, which would be thinner than a 10 weight oil when cold. That's the number to look out for when trying to prevent cold weather 'dry' starts that can cause bearing and cylinder wall wear. However aside from climate, bearing clearances will also dictate what oil weight to run.

The second number is the hot temperature protection rating, which on a turbocharged vehicle is really important. In this application a 20 rating would not provide the protection needed when the turbo gets hot, especially after spirited driving. This is where oil coking comes in and can cause oil flow issues as well.

For a completely stock SRT-4, 5W-30 is sufficient. However anybody that drives their car hard and/or is running higher amounts of boost or a big turbo really should be using at least 5W-40 IMO.

Look at the following chart - look at the low temperature for your area. Do you really need the left number to be anything but 10W? 20-50 is usually a kind of race grade oil. Fortunately with synthetic oils there is great flexibility in temperature suitabiltiy, but a 10w-30 oil would be a better choice. There isn't likely to be any damage to your engine.
