I tend to go too long between oil changes and this product has definetely helped keep my 13 year old truck on the road.

[This review was collected as part of a promotion.] I have used in my older truck for years. 400k miles and still running strong!

Use this in my 89 Ford Crown Victoria LTD with 175,000 miles. Still good oil pressure less than pint low at 5,000 miles.

I use this brand and had hole in oil pan,drove my car for two days before I knew anything was wrong,kept motor alive!!

I've been using this in my Dodge RAM 1500 since the truck hit around 90K, now it's still going strong with double the miles on today.
