Synthetic Oil vs Conventional Oil - Which Type Is For Your Car Engine - Groom Your Vehicle

one, two, three, four! Rev up your engines! It's time for the Scotty Kilmer Channel today I'm going to talk about what oil you should use in your car, now I've been working on cars for the last 50 years, things have changed both in terms of oil and the engines they go in, so I'll give you the skinny on what you need to know, now check your oil cap, even though this car is 24 years old, it says on the cap, use 10w30 oil, but of course, there's millions of different kinds of oils out there, so which one are you going to use, now in my case I just used conventional 1030 Castro oil, I like Castro, and since I don't drive much, I change it once a year, because it does wear out as you can see I'm charging up the battery, last year I only put 600 miles on the car, but if I was going to use a synthetic oil in this, one it would be a waste of money, because you still got to change it once a year, and two, I've talked to engineers and they tell me it's impossible, but I've seen it too many times, guys will get an old car like this, and it's 240,000 miles, they put in synthetic oil, then it will either leak more oil or burn more oil, so I'm not switching an old car from using conventional oil high mileage, to using synthetic oil, I just wouldn't do it, because I've seen problems occur then, now let's go to a more modern car, this Toyota Matrix has a cap that says use energy concerning 5w30 oil, now here you have a choice, you can use either regular oil and change it say every 5,000 miles, or you can use full synthetic oil, and you can push it up to eight or ten thousand miles then, now this used to be my wife's car, and she drove it to school, so she put about five thousand miles a year on it, so I just used normal oil and it changed every 5,000 miles, but if you have a car like this and you drive a lot more mileage, you could use synthetic oil and change it a lot less often, then you'd get to decide what synthetic oil to use, well my theory with that is, go for the one that's the lowest price, when I went to Autozone, the Mobil one was like 10 bucks a quart, but this STP full synthetic one was only five dollars a quart, so I use the STP what the heck, now in many really modern cars, they use a 0w 20 oil, now that, you have to use a synthetic oil, because it's only available in synthetic oil, 

So my advice to that is, hey go price around find the one that has the best price and use that one because you have to realize at least here in the United States, the government has all kinds of regulations on motor oils these days, so any that are sold are perfectly fine there aren't any crappy ones that are being able to be sold to the public in the United States, now lately a lot of people then asked me about this Mobil one annual protection oil that can go 20,000 miles or one year, well here's the truth about that, first you have to go down and read the caveats, and one of the caveats is, 20,000 miles or one year but please follow the recommendations in your owners manual, because it may void your warranty if you go more than the mileage they suggest, and truth be told you can only do 20,000 mile oil changes if you do mainly highway driving, you really can't do that and stop and go city driving, those big truckers they don't change their oils that often, but the trucks are going 65 miles an hour for hours and hours on edge and there's not much wear in an engine when you're going at a steady speed on a highway, so me if I'm going to use synthetic oil, I'm going to find the one with the best price, change you to every seven to ten thousand miles, so now you know what you need to know about motor oils, buy the right one at the right price, don't waste your money, but don't ruin your engine, and remember if your car has any problems just visit the Scotty Kilmer channel, before it's too late!
