My GX on the recent service with Greenville and managed to look at the service, I was amazed to see that they were using WYNN'S Service Kit. Why would they use it? Any ideas ? Why would a Lexus dealer use a non OEM brand product on the Lexus vehicles, Are we saying Toyota do not have such kit or products. Here I am not against Wynn's product, they are good, but what does it mean, dealer is saving costs to get vehicle serviced at lower cost products available in the market than using toyota product.
