Warranty Details (30 DAY REPLACEMENT IF DEFECTIVE)
Castrol GTX High Mileage 5W-20 is specially formulated for vehicles with over 75,000 miles. It's a synthetic blend engine oil formulated to provide Superior Protection in 7 Critical Areas including corrosion prevention, sludge control, timing and friction wear and unique protection for your emission system. As your vehicle ages, it becomes more prone to catalytic converter failure, one of the most common and costliest problems faced by higher mileage vehicles. All motor oil contains phosphorus to prevent engine wear, but phosphorus is known to be effectively poisonous to catalytic converters. Castrol GTX High Mileage 5W-20 is formulated with Phosphorous Replacement Technology, a proprietary additive that reduces the level of harmful phosphorus to protect the catalytic converter and preserve the life of your emission system. It also includes specialized additives to reduce leaks, oil burn off and power robbing deposits. Castrol GTX High Mileage 5W-20 provides maximum protection to help extend the life of your high mileage car.

Product Features:
  • Phosphorus Replacement Technology to help extend the life of the emission system
  • Superior dispersancy that fights sludge build up
  • Exceptional oil burn-off protection exceeding industry standards (1)
  • Seal conditioners to help reduce leaks
  • Advanced additives that minimize engine wear

A good quality oil for high mileage SUVs
I change the oil and oil filter every 5000 miles in my SUV that is over 130,000 miles. This is a quality oil that is not too high priced. Advance Auto gave me a discount for buying this particular oil and a particular brand of oil filter which is anonymous together for a discounted price. Also, I sent for a free NFL cap which was part of the offer.
Most Liked Negative Review

Would buy again for sure
Verified Buyer -
A very good synthetic blend oil that offers better protection driving in the city or hwy driving than just plain conventional oil in my opinion only. I also use this in my 1996 gmc pu truck. It also helps with oil leaks which is a big plus for older vehicles with 75,000 or more miles on them. Was put in a 2000 chevy cavalier 4 cyl.
Bottom Line Yes, I would recommend to a friend
My go to oil
