Tps won't serve me

trade only, i could used to get Synta oil and filter and air filter for 20 of a mechanic but he has now retired. An tips on getting served at tps?
But I will only do @ 1500 miles a year and she will be put to bed end of September for the winter. I will change it again the following spring.
I will let u know in 12 months if my engine is still ok
