Yeah. I was worried about carbon build up because I drive a little focus daily and run 91 ethanol free gas. I also use the pennzoil ultra platinum full synthetic oil and change it every 3,000 miles. I’m just not sure when I should go in there and expect to see carbon building up.Asking about motor oil brands is too broad. There are numerous motor oil products and compositions that meet different standards for different applications. It’s a little like asking about brands of gasoline. Any top tier gasoline of the appropriate octane rating (resistance to combustion) for your vehicle (factory or tuned) will get the job done. There are some special cases where specific detergent formulas may be beneficial over time, but for most people just going with any tier one brand of gas for their Corolla or Tahoe or whatever is going to be just fine. Saying Exxon gas is great while Chevron is awful or that Valero has the best gas starts getting a little silly. Get it from a high volume station, and when in doubt go with Shell V-Power Nitro+
I also like to run it to redline a bunch of time each day (not doing this for a particular reason, it’s just fun to beat the piss out of these pos cars). Anyway not sure what I should to to improve engine life and power. Thanks.
