Here is the analysis:
Driving conditions:
I fall under the severe service interval. I live in Manhattan and I take weekly trips to school out to Suffolk County, Long Island, about 55 miles each way. The car has seen plenty of stop and go traffic,(LIE and BQExpressway) and red lights, when I'm looking for a parking spot around my home. Sometimes I'm stuck for an hour or so in traffic. Once on the highway I do around 60-65 @ 2.5-2.7k rpm.
Maintenance:
An oil filter magnet was used and the EAO oil filter was changed out at 5000 miles. This is due to Amsoil's new OEM invterval policy on toyotas. The remaining 1000 was on a Mobil1 filter. There is a total of 117,000 miles on the dash.
Thoughts:
I realize that this is a tired old engine and it likes to drink motor oil. (About 1 quart per 3000 miles) I've had new valve guide seals put in, which stopped a blue puff of smoke on initial startup in the morning. It has stopped an visible burning of oil at the exhaust. I reason now that I am still getting blowby from either bad piston rings or the guides are getting ready to go. (Yes, I've changed the PCV valve.)
Anyway, I would like to hear recommendations for a cheaper synthetic. I've had my eyeball on Walmart's Supertech Synthetic brand. I'll prefer to have the synthetic since its easier on the engine on cold startups.
Seeing as I can barely reach the 10,000 mark without burning tons of expensive oil, I was hoping to know 5000 intervals with supertech syn and a puralator filter would be safe for my vehicle.
I'll take any input.
