Jiffy Lube damaging engines while “flushing” them
Wednesday, November 26th, 2008

One of the unfortunate situations that has taken place at Jiffy Lubes in Southern California, is the process of “engine flushes”. It appears that there was, (until 2 weeks ago), an incentive in place for some of those shops to sell “engine flushes”. We did see the report on a local L.A. news channel and it was pretty scathing. Now, there have been hundreds of complaints to the Bureau of Automotive Repair and damaged engines. As one who takes pride in our industry, this was very, very sad to see.
Reality check: Regarding one of those “jiffy/quicky” lubes in our area, our oil service is only a few dollars higher priced than theirs for BMW. …

Flush your brake fluid and stop on a dime
Saturday, November 1st, 2008

The syndicated automotive news publication Wheelbase Communications, recently conducted some testing that involved both Tire Rack, Goodyear Tire and Brembo brakes. The test results surprised most of the participants due to the fact that there was a substantial difference in braking performance after a routine brake fluid flush. This comes as no surprise to people who love to drive the heck out of their BMW. We’ve known this for some time, but it’s good to see it in black and white.
The new brake fluid enhanced the stopping distance in the tests conducted, “before and after”. That’s because over time, the brake fluid breaks down, heats up and becomes less effective. In other words, after …

Getting nailed: a cautionary tire tale
Tuesday, October 21st, 2008

We have mentioned that sticker on the inside of your BMW’s door jamb as having your recommended tire pressure. Keep in mind that those numbers are PSI when your tires are cold. That means, check those tires before your leave your driveway in the morning. Driving will increase the PSI about 6 to 8 PSI, as will a temperature increase during the day.
Once again, we are reminding you that a Tire Pressure Monitoring System does not, and will not, take the place of a physical inspection of your tires. (An incident that we recently experienced, tells the whole story). We were with family members hopping into a 2008 brand new vehicle for a drive that …

Give me a thick brake. And no turning!
Wednesday, September 24th, 2008

We’ve seen some (brake) rotor warping , recently, that was due to improper torqueing of wheels. The culprit is usually an impact gun, being used in, let’s say a harsh way. The result will be a shimmy in the steering wheel when you press down on the brake pedal. Not good.
BMW specs require that rotors be replaced when doing a brake job. There was a time, (long ago in brake lathe land) when rotors were “turned or machined”. Not the case with BMW’s for some time.
OK, why not machine the rotors? After all, isn’t that a less expensive way to go? Glad you asked that question.
The machining or turning of the rotors will …

Tire that takes a hit – once and for all
Thursday, September 11th, 2008

Have you seen the Bridgestone TV ad, (featuring a BMW), for their Run Flat tires? It’s a dramatic example that demonstrates how the tires can take a large nail and not deflate. Run flat all-season tires are available or standard on many of the 2009 BMW’s.
Keep in mind that these tires are not repairable, as is the case of some tire punctures. The idea is that you can safely drive to a place where you can get a replacement. It beats trying to change a tire in the heat, snow, rain, or whatever, on the side of the freeway. OK, so you just call the tow driver if you have a flat.(Have mercy)

Picking corners to cut
Monday, August 25th, 2008

A veteran financial expert and writer, Marshall Loeb, recently identified 4 primary areas where consumers should not reduce their expenditures, (during tough economic times). He cited “Where NOT to Scrimp”, in a recent article.

Car Maintenance
Safety for the Home
Faster Internet Connection
A comfortable Mattress

His article, cited, do not “ignore any potential problems, out of place sounds or oil leaks. Delaying dealing with these issues may only cost you more in the end when they become larger problems.”
We couldn’t have said it better. A reminder to take care of those safety related items first. Tires anyone?

Keeping your grooves clean
Wednesday, August 6th, 2008

If you have been driving or living near some of the wildfires and the affected areas, you may want to check the condition of the air filter in your BMW, MINI’s or other car. Yes, even if it’s not “time” for it to be checked.
Recently, we saw an air filter that was seriously full of what looked like burnt pine tree, particulate matter. It felt like it was covered with an oily substance and there were small chucks of wood, in the groove, and it was black! The fuel consumption was excessive and resumed to normal, (which is great as you MINI owners know), after replacing the dirty air filter. Yes, this car was perilously close to the fires and …

BMW giveth and taketh away
Wednesday, February 20th, 2008

Well, the figures are out and there was a 30% increase in total vehicle manufacturer recalls from the previous year. (Does that make you want to keep your current BMW or what)! That was a whopping 15 million vehicles. The increase may be due in part to legislation that was designed to have safety issues addressed as quickly as possible and issue a subsequent recall if necessary.
So, the bad news is that there was a substantial increase in vehicle recalls. The good news is that you found out about them sooner.

Making a splash? – Check your shield.
Wednesday, February 6th, 2008

The front, lowest part of the body on your BMW is your “splash shield”. If you should run over something, this part can sometimes sustain damage. Some of the parts that go along with this scenario could be fog light wires and ambient temperature sensors. If you run over something, take a look at that area. You may see scratches, but hopefully, no wires were knocked loose, (as can sometimes happen). Scratches, you may want to live with. But, wires dangling, get this looked at by a BMW professional.
Just this morning on the way here, we saw a gorgeous, late model 740il with wires hanging down in front of the tires, (on each side …
