I bought some costco diesel in Prescott AZ and was told by the attendant that only three stores in the country have it. Dan

I typically don't read or post in additive threads but I will say this, If your engine has a sludge, consumption or a ticking noise problem try some additives like seal conditioner HM oil or a cleaner additive and maybe you will find one that works. Other than that there is no need to use the...

The only way to know when to change filter is to a switch connected to a light added to the filter bypass valve letting you know when it is bypassing. If it is bypassing when the engine is fully warmed up it's time for a new filter. Dan

Your 3000/3 month OCI sounds like the severe sevice. Read and check the book again. Dan

I too am a fan of brad penn. I would run their 10w-40 penn grade 1 year around. An oil with lots of zinc like a diesel oil is not the whole picture, it's the balance of zinc and other adds that matters. Dan

Many HP cam grinders recommend dino racing oil in high valve spring tension performance engines. They report fewer cam failures and longer cam life with dino. This would not apply to a stock engine and syn oil is superior in that app. Dan

Yes it has plenty of ZDDP. Good choice IMOP, I think it will only be good down to somewhere in the 30-40F range. If it gets cold buy the VR1 10w-30 flavor. Dan

Scion FRS.

At 155k you need to have all of your injectors professionally off the vehicle cleaned. No need to buy new ones. Contact RC Engineering. I have seen engines destroyed from ignoring dirty injectors. The only right way to do it is off the vehicle. Dan

Rotary's are dead with the big push for max fuel economy. Too much internal surface area to absorb combustion heat energy which only heats up the radiator and is not used to move the car. IMHO diesel is the future of IC engines. Just drove the new Chevy cruze diesel, nice car. Dan

Of coarse it's better because it's purple and my Brad Penn is better because it's green doesn't everybody know that?

I am so sick of seeing 540 RAT's oil test all over the internet. It is bunk. The best way to test an oils anti wear ability is to test it is in a running engine. Any thing other than that is measuring the gas mileage of a Caddy going down hill or measuring the wattage of a stereo amp driving a...
