I have used Castrol GTX for over 20 years in every car I have owned.
However ,when I took my new car in for it's first oil change I was informed that Hyundai had made a deal with Quaker State.
I have never had much love for Quaker State , but seems that they agree to extend the engine warranty (all moving internal parts) to 250,000 miles as long as you use their oil and change it within their recommended 4,000 mile limit.
Since I purchased the 2 year ,24,000 miles service plan ,I have continued to use this oil.
But when I reach the 27,000 mark I have thought about changind to a full synthetic.
I know everyone has their own opinion ,but I would like to know what everyone recommends on oil and filter.
Here the temps rarely see 10 degrees F in winter ,and often see 90-100 in summer.
Thanks in advance,
Thomas :whistling:

My first oil change I did on my car was with AMS Oil Full Synthetic. After that I change it every 6000 Miles with Royal Purple 5W30 oil. Have yet to have a problem. Have over 37,000 miles on the car too. Every other oil change I also use the Lucas Fully Synthetic Oil Stabilizer. (The one in the black Lucas Bottle). However on the new Elantra I just bought I have a deal with the dealer to do the first 4 oil changes for free. But after that I am going with a full synthetic.

OK, heres what I know about oil.
If using synthetic, you can go 7500-10000 miles between changes easily.
If using conventional you can easily go 5000 miles between changes.
Most synthetics are a group III base oil synthetic. Which is just a very highly refined and hydrocracked mineral oil. Such as Mobil 1, Pennzoil Platinum, Valvoline Synpower, and a host of other brand names. A group IV synthetic is the real deal, such as amsoil. You can carry out a group IV oil change far past 10000 miles.
If you change your oil out at around 5000 miles just stick to conventional. Otherwise your wasting your money.
OK heres what I use. Valvoline Synpower in a 5w30 weight and a purolator Premium Plus oil filter. I take it about 6000 miles between changes.
You can really confuse yourself at www.bobistheoilguy.com when you really want to know about all brands of oils and filters.

I saw in the manual where Hyundai recommends Quaker State. I used to use it a long time ago...

I've had mine changed at 3 different dealers... The dealer I bought it from uses Valvoline 5W20, another dealer who also sells Chryslers puts Mopar 5W30 oil in there (whoever makes that) and the last dealer I went to uses Valvoline 5W30.

I've always been partial to Pennzoil for dino juice and supply the dealers with that. This last time though, I just let them put in whatever and didn't bother bringing in my own (that's the dealer that uses Valvoline 5W30.) Haven't noticed any significant change in FE on the 5W30 thus far, guess it works good enough.

I could run synthetic, but no matter how good you tell me the oil will hold up, I'm still skittish about really long change intervals. So, if I'm going to be changing oil every 5-6K on Synthetic like I know I would, I'll just stick with 3K dino juice changes.

OK I can do one of two things here.

1. Type a few very large reasons to go synthetic, the differances between oils, information about extended drain intervals, Why you can go up tp 40,000miles on a single oil change. etc. etc

2. Or I can just put up a link that will for ever answer any lubrication question you might have.

I'll do number 2. you can look
Questions, Myths, and Information about synthetic oils and more..

12,500 Km is to XL series of oil from Amsoil. That's the shortest change interval, if you go with the Signature Series you can get up to 56,000km or you can really go crazy and get the By-Pass filters and go until oil testing tells you to change it.

By the way here's an interesting report on gear lubes, check where Royal Purple stands.

Here's an interesting fact and letter from the CEO on that pantent for that phrase.

AMSOIL is "The First in Synthetics" and also the first in quality, protection and performance. Every other oil company in the world was given the chance to object when AMSOIL applied for trademark rights to "The First in Synthetics", yet after 90 days of waiting, not a single one objected!

The U.S. Patent and Trademark Officials stated that by claiming that AMSOIL was the first historically, that AMSOIL was also insinuating to be the best (or #1/first) from a quality or performance standpoint. AMSOIL showed the government officials comparison documentation and test data backing up the claim that AMSOIL was also the best.

After the government officials notified all other oil manufacturers that AMSOIL was claiming to be the best, not a single other oil company or competitor objected! Not a peep from any of them! I can guarantee you that if any of these competitors and major oil companies had a product better than AMSOIL they would have objected.

AMSOIL - "Our Company makes the Best Lubricants in the world, period, and challenges anyone or any company to prove us wrong! That won't happen because our competitors know it's true."

A. J. Amatuzio, President and CEO.
