I told me friend I was interested in feed back on his oil change regimen. It's different than most. The OCI's are fairly short so maybe it doesn't matter at all. He's not a Bitoger type. I recommended some filters and oils to him but he's fairly happy with what he's doing. Comments welcome.
The cars: 5 Toyota product cars 1999-2000 models have between 101,000-194,000 miles , and were well cared for, before we got them,
We bought them from 2010-2015.
2 are 3.0 liter V-6, Avalons, 99 & 2000
3 are 4.0 liter v-8, Lexus GS400, one-1999 & two - 2000
These cars are freaky in that almost every time I get gas, and I gas all five of our cars, I check the oil. They don't burn, or lose oil, anywhere, during the oil change cycle, & to me, that's freaky, for cars that are this old.
They are all 100% stock. Combination of short and long trips in warm Orange County, California.
Regimen for the past 2 years:
1 quart generic 10-30 full synthetic, currently STP 10-30 full synthetic
1/2 quart, Double concentrated Rislone engine treatment
Mechanic fills in the rest with his 5-30 conventional bulk Mobil.
And he uses his own oil filters, some no name brand, he swears by, as being good, no name filters.
I go 3,000-6,000 max but most frequently go 2,500-4,000 between oil changes, with him. Note that prior to 2 yrs ago he just filled with conventional oil at the mechanic's shop - no additives, no mixing. He said some of the cars (Avalon) were using up to 1/2 qt per 3,000 miles. Now, zero usage.
MMO in the gas tank, about 8 ounces, per 19 gallon fill up, every 4th fill up.
