Another Happy Customer!

So happy I found RockAuto! My days of overpaying at brick and mortar stores is done. I am an average working guy trying to keep three cars maintained for my family. With the savings from RockAuto...I feel confident they are safe on the road and we are not going broke writing checks to dealership service departments.

Repair Mistakes & Blunders
Repair Mistakes & Blunders

After high school in the spring of 1970, I went to work at my brother's service station. One day, my brother was servicing a Dodge Charger, and I was shocked when I found out it belonged to my driver's ed teacher from high school. My brother had to leave and asked me to finish putting the remaining two wheels on the Charger. Wanting to impress my former teacher, I made an extra effort to make sure I torqued the wheels by the book and cleaned the car up nicely. My teacher picked up his car and seemed very satisfied until he walked(!) back to the service station about 10 minutes later.

His normally cool demeanor gave way to behavior and language I did not know a school teacher could possess! Apparently my brother had only hand tightened the lug nuts on the two wheels he installed and assumed I would tighten them. I did not. After driving a few blocks, one of the Charger's wheels came off and the other was just about to. Amazingly, there was no serious damage, and everything was fixed to his satisfaction.

Lessons learned:

  1. Finish what you start before handing a job off
  2. If #1 is not possible, make sure you communicate exactly what has been completed
  3. Never assume anything (ask questions when taking over a job)

A New Oil Specification for GDI Engines
Tom's Story

This year brought us a new specification for motor oil; ILSAC GF-6 / API SP. One of the primary goals of the new oil spec is to reduce incidence of two problems gasoline direct injection (GDI) engines have been experiencing.

GDI blasts the fuel directly into the combustion chamber at high pressure. This leaves less time for the air and fuel to mix together. The resulting air/fuel mixture may burn unevenly which may generate a lot of soot. As the pistons move up and down, the soot gets mixed into the motor oil. The soot travels with the motor oil through the engine and causes wear.

The most noticeable wear often occurs between the pins and bushings that hold timing chains together. As the bushing holes wear and enlarge, the timing chains stretch. Eventually the timing chains may stretch to the point that they slip across gear teeth or otherwise are unable to correctly connect the crankshaft to the camshafts. The computer generates a trouble code, the engine goes into limp-in mode and/or the engine stops running. GF-6 / SP oil resists collecting and circulating the harmful soot.

The second problem, low-speed pre-ignition (LSPI), is also related to the uneven burning of air/fuel in GDI engines; specifically, turbocharged GDI engines. When running at relatively low RPM and under heavy load, like when moving away from a dead stop, severe knocking may occur inside the cylinders. Scientists figured out that traces of engine oil mixing and burning with the air/fuel mixture contributes to the damaging engine knock. GF-5 / SN-Plus spec oil was released a couple of years ago to combat this problem (watch for the “Plus” after SN). The new GF-6 / SP oil helps with both the soot and knock problems.

Ford has produced the most turbocharged GDI engines. Small 1L, three-cylinder Ford EcoBoost engines power Ford Fiestas, and big 3.5L, six-cylinder EcoBoost motors are in work trucks that rack up a lot of severe-duty (towing, dust, etc.) miles. The soot and knock problems have been studied most thoroughly on EcoBoost engines. The new specification actually requires that new GF-6 / SP oils pass tests running in Ford EcoBoost motors!

These new oils, higher fuel injection pressures, intake manifold port injection coupled with GDI, etc. help solve these problems on older engines and prevent them on newer engines. GDI engine owners may be able to help the most by simply changing their vehicles' motor oil frequently and always using the correct oil. Instead of waiting for the longest, light-duty, oil change interval (often 7,000+ miles/11,000+ km), change the oil closer to the severe-duty interval (often 3,000 miles/5,000 km).

You can check to see if your specific vehicle's engine uses GDI by looking at the “Info” pages and part descriptions for the engine's Fuel Injectors found under “Fuel & Air” in the RockAuto.com catalog. Find the correct engine Oil for your vehicle under “Engine.” Oil is also listed by viscosity/weight under the “Tools & Universal Parts” tab.

Note: The “A” in GF-6A means the oil is a viscosity/weight compatible with existing engines. The “B” in GF-B means the oil is only to be used in recent engine designs that require completely new viscosity/weight oils such as 0W-16.

Andrew's 1986 Buick LeSabre Grand National
Andrew's 1986 Buick LeSabre Grand National

This is my 1986 Buick LeSabre Grand National. Not to be confused with the Regal Grand National, this car was solely built to qualify the LeSabre body for use in NASCAR. Only 117 were built in late 1985. This particular car was one of the last built and converted according to the VIN.

LeSabre Grand National models were outfitted with a special front spoiler for aerodynamics, as well as unique NASCAR rear quarter windows. They featured the naturally aspirated 3.8 liter V6 in front wheel drive configuration and of course had Grand National badging on the fenders with a solid red Power 6 logo instead of the typical yellow and orange variant found on the turbo Regals of the era.

I obtained this car from a friend and it was in sort of rough shape, but it was a rust free example originally from Tennessee. Every part of the car was touched -- anything that needed replaced, got replaced, and anything that needed refinished, got refinished or freshened up. This is also the first car I ever did a complete paint job on rather than just one or two panels.

Almost all of the parts I got were from RockAuto; specifically engine and suspension parts, engine and trans mounts, belts, hoses, gaskets, spark plugs and wires, struts, sway bar links and bushings, exhaust hangers, carpet, lug nuts -- the list goes on!

Thank you very much!
